2015-04-01mtd: nand: do not scan BBT after scrub2014.10-toradex-nextMasahiro Yamada
Currently, "nand scrub" runs chip->scan_bbt at the end of nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set. It violates the intention of NAND_SKIP_BBTSCAN. Move NAND_SKIP_BBTSCAN flag check to nand_block_checkbad() so that chip->scan_bbt() is never run if NAND_SKIP_BBTSCAN is set. Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt() right after scrub. We can be lazier here because the BBT is scanned at the next call of nand_block_checkbad().

2015-04-01mtd: nand: Mark the BBT as scanned prior to calling scan_bbt againMasahiro Yamada
Commit 35c204d8a9d0 (nand: reinstate lazy bad block scanning) broke NAND_BBT_USE_FLASH feature. Its git-log claimed that it reinstated the change as by commit fb49454b1b6c ("nand: reinstate lazy bad block scanning"), but it moved "chip->options |= NAND_BBT_SCANNED" below "chip->scan_bbt(mtd);". It causes recursion if scan_bbt does not find a flash based BBT and tries to write one, and the attempt to erase the BBT area causes a bad block check. Reinstate commit ff49ea8977b5 (NAND: Mark the BBT as scanned prior to calling scan_bbt.).

2015-03-18arm: vf610: fix boot from SD-cardStefan Agner
Boot from SD-card (and probably also from NAND) was broken since commit d6d07a9bec ("arm: vf610: add NAND support for vf610twr"). It looks like the increased size of U-Boot lead to a situation where the boot ROM overwrote its own stack/heap while loading U-Boot from the SD-card to the SRAM. However, U-Boot worked fine when loaded through USB serial loader directly into SRAM. It looks like loading from SD-card uses other stack/heap location then the serial loader (or maybe no stack or heap at all). This fix moves U-Boot to gfxRAM, which is 512kB in size and is not used by the boot ROM nor the SD-card loader of it.

2015-02-19fs/fs.c: read up to EOF when len would read past EOFMax Krummenacher
http://lists.denx.de/pipermail/u-boot/2012-September/134347.html allows for reading files in chunks from the shell. When this feature is used to read past the end of a file an error was returned instead of returning the bytes read up to the end of file. Thus the following fails in the shell: offset = 0 len = chunksize do read file, offset, len write data until bytes_read < len The patch changes the behaviour to printing an informational message and returning the actual read number of bytes. (cherry picked from commit 4641b92713300089c5980259ba31e668657aa75d)

2015-01-07mtd: vf610_nfc: allow bitflips in an empty pageStefan Agner
Allow bit flips in a empty page up to half of the recoverable bits (strength / 2). Some flash show bit flips in empty pages which are larger then the corrected bit count according to the ECC controller. It is not yet clear how to solve this correctly, discussion is ongoing: http://thread.gmane.org/gmane.linux.ports.arm.kernel/295424 Since we habe a 24-bit correction, this allows up to 12 bit flips on a empty page before reporting it as page with ECC errors.

2014-11-19colibri_vf: switch to Thumb2 buildsStefan Agner
Switch to Thumb to builds which are considerable smaller: 415512 19. Nov 14:52 ../u-boot-toradex/u-boot.imx vs. 313112 19. Nov 14:55 ../u-boot-toradex/u-boot.imx Especially download time through serial loader is linearly to size, hence download time is faster by 25% too.
2014-11-19arm: make arch memset/memcpy to work with Thumb2 buildsStefan Agner
Resynchronize memcpy/memset with kernel and build them explicitly in Thumb2 mode (unified syntax). Those assembler files can be built and linked in ARM mode too, however when calling them from Thumb2 built code, the stack got corrupted and the copy did not succeed (the exact details have not been traced back). Hoever, the Linux kernel builds those files in Thumb2 mode. Hence U-Boot should build them in Thumb2 mode too when CONFIG_SYS_THUMB_BUILD is set. Also add implicit-it=always to AFLAGS when building for Thumb2. Furthermore add no-warn-deprecated option to AFLAGS to rid of deprecated unified syntax: arch/arm/lib/memcpy.S: Assembler messages: arch/arm/lib/memcpy.S:153: Warning: conditional infixes are deprecated in unified syntax arch/arm/lib/memcpy.S:154: Warning: conditional infixes are deprecated in unified syntax ...

2014-11-18colibri_vf: calculate and set secondary MAC addressStefan Agner
In order to support dual ethernet configurations, a second MAC address is needed. Toradex assignes two addresses for each module, one address is the serial number, and the second is the serial number with an offset of 0x100000.

2014-10-28net: asix: fix operation without eepromMarcel Ziswiler
This patch fixes operation of our on-board AX88772B chip without EEPROM but with a ethaddr coming from the regular U-Boot environment. This is a forward port of some remaining parts initially implemented by Antmicro.
2014-10-28arm: vf610: extract leveling parameter in a structStefan Agner
DDR leveling parameters are board specific, hence we should be able to set them differently per board. Extract the leveling parameters in a seperate struct to be able to set them per board.
2014-10-28arm: vf610: improve DDR initializationStefan Agner
With the new JEDEC standardized initialization parameter, the initialization takes longer than 200us. Use the status bit to determine whether the memory initialization was completed. Also use recommended JEDEC defaults for t_INIT.
2014-10-28colibri_vf: use PLL1 as DDR clock on VF50Stefan Agner
On VF50, we can use PLL1 as DDR clock since the CPU is clocked with 400MHz as well. This saves some power (measured around ~10mW).

2014-10-23Revert "dm: tegra: Enable driver model for serial"Marcel Ziswiler
Migrating our BSPs towards mainline U-Boot I noticed it suddenly booting slower. With mainline Linux I noticed about a 1 to 2 second increase while booting downstream L4T takes 10 to 15 seconds longer! This reverts commit 858530a8c0a7ce7e573e513934804a00d6676813. Conflicts: drivers/serial/Makefile
2014-10-23colibri_vf: synchronize environment with i.MX6 U-BootStefan Agner
Synchronize environment with i.MX6 U-boot. Load device tree unconditionally, but set parameter to device tree file only when loading succeeded. Also load the device tree when using SD or NFS boot.
2014-10-23colibri_vf: fix environment for NFS/SD-BootStefan Agner
Switch to zImage for SD and NFS-Boot. Explicitly define the load address in all commands.
2014-10-23colibri_vf: extend environmentStefan Agner
Newer UBI implementation do not allow small UBI partitions since the amount of bad blocks is now calculated by the size of the MTD partition (instead volume size). On small partitions, this leads to UBI partitions only consisting of reserved blocks. Therefor we now use only one volume, which also allows better wear leveling and bad block management. Since it is needed to attach the whole UBI partition, mounting the UBI filesystem would be a good option. Measurement showed that the overhead reading from UBI filesystem compared to read from a UBI volume is minimal (below 100ms). Furthermore, this also adds support to load device trees for newer, device tree based kernels. By setting the variable fdt_board, the scripts read the FDT file and try to pass this to the kernel. The FDT file will be concatinated: ${soc}-colibri-{fdt_board}.dtb E.g. when fdt_board is set to "eval-v3", the scripts will load the device tree file "vf610-colibri-eval-v3.dtb" on a Colibri VF61.
2014-10-23arm: vf610: add SoC detectionStefan Agner
Vybrid product family consists of several rather similar SoC which can be determined by softare during boot time. This allows to use the variable ${soc} for Linux device tree files.
2014-10-23arm: vf610: enable cachesStefan Agner
Enables caches which provides a rather huge speedup of the boot loader. Also mark the on-chip RAM as cachable since this is the area U-Boot runs from.
2014-10-23colibri_vf: disable automatic boot when using recovery modeStefan Agner
Since we use the same UART to download U-Boot and get the U-Boot prompt, it is quite hard to switch between the download program and the terminal emulator within the boot delay. This patch disables the automatic boot by setting the bootdelay to -1 when using the recovery mode (serial downloader).
2014-10-23vf610: improve CPU type detectionStefan Agner

2014-10-23colibri vf50/61: detect bad blocks in U-Boot areaStefan Agner
The boot ROM was not able to detect bad blocks in the U-Boot area due to disabled "bad block marking swap" functionality. The description of this field is a bit unclear, but tests show that skipping bad blocks in U-Boot area only work if this field is set to 0.

2014-10-17arm: vf610: initial integration for Colibri VF50/VF61Stefan Agner
This adds initial support for Colibri VF50/VF61 based on Freescale Vybrid SoC. The board support package is based on Freescale Tower board, with following differences: - CPU clocked at 500MHz - Use PLL2 as DDR3 clock (400MHz) - New Machine ID - Console on UART1 (Colibri UART_A) - Ethernet on FEC1 - Enabled command line editing - PLL5 based RMII clocking (e.g. no external crystal) - UART_A and UART_C I/O muxing - Boot from OCRAM gfxRAM - Boot from NAND by default Tested on Colibri VF50/VF61 booting using serial loader over UART.
