Add an explicit cast to avoid the following build warning:
colibri_vf.c:225:23: warning: initialization makes pointer from integer
without a cast [enabled by default]
|
|
Now as the colibri_vf61 configuration supports memory size as well as
module type auto detection actually rename it to colibri_vf to be
universally used for Colibri VF50 as well as VF61.
|
|
Implement module type (e.g. VF50 vs. VF61) auto detection based on L2
cache availability. Set specific ARM core clock (e.g. 400 vs. 500 MHz)
as well as Linux machine id number.
While at it actually use memargs instead of hard-coded mem= value.
While at it fix sdboot command if initially booting U-Boot from NAND by
doing an explicit mmc part 0.
|
|
Implement memory size auto detection including memargs generation
analogous to how it was done for Apalis/Colibri T20/T30.
While at it make our board file checkpatch compliant.

Add initial Colibri VF61 support based off Timesys' implementation for
Freescale's Vybrid Tower System TWR-VF65GS10:
- New machine ID.
- Default UART_A on SCI0.
- ESDHC2 only.
- 8-bit NAND.
- No quad SPI.
- FEC1 only.
- Enabled command line editing.
- PLL5 based RMII clocking (e.g. no external crystal).
- UART_A, UART_B and UART_C I/O muxing.
- Increase the available space for the U-Boot binary to half a megabyte
by booting from gfxRAM rather than sysRAM0.
- Integrate factory configuration block handling for hardware version,
MAC address and serial number to be passed to Linux.
- The U-Boot environment is stored in NAND flash.
- Fix long standing boot hang issue introduced by Freescale's Vybrid
1.1 silicon.
- Proper 256 MB Nanya DDR3 RAM timings.
Tested on early Colibri VF61 prototypes V1.0b and V1.0c using SD card
(mandatory for initial loading) as well as NAND boot.

Correct Answer

For the record:
DDRMC_CR154 needs to be 0x682C0000
before was: 0x68200000
There was a change from Si 1.0 to 1.1. So this only affects Si 1.1 and
this version requires writing this value to the register.

Fix possible uninitialised array member issue in serial number to
hexadecimal coded decimal conversion routine.
|
|
Migrate to default NAND boot configuration (e.g. colibri_vf50_config)
and SD card boot on request (e.g. colibri_vf50_sdboot_config).
Automatically do the padding required for NAND boot image
(e.g. u-boot.nand).
This is also more in-line with how we did stuff back on the Colibri
T20.

|
Integrate factory configuration block handling for hardware version,
MAC address and serial number to be passed to Linux.
The U-Boot environment is stored in NAND flash.
Default is to boot out of NAND flash using the UBI abstraction.
Optional NFS as well as MMC/SD boot variants are also available.
This brings the configuration more in-line with our Tegra based
versions.
While at it enable board size limit check set to 512 KB related to the
gfxRAM area of the OCRAM.
Please note that a boot delay of zero did not quite work the same way
as on the Tegras where one was still able to interrupt the boot process
by continuously hitting a key. Therefore set it to one second for now.
