2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-06-07rockchip: mkimage: force 2KB alignment for init_sizePhilipp Tomsich
The Rockchip BootROM relies on init_size being aligned to 2KB (see https://lists.denx.de/pipermail/u-boot/2017-May/293268.html). This pads the image to 2KB both for SD card images and SPI images and uses a common symbolic constant for the alignment.

2017-06-07rockchip: mkimage: add support for verify_header/print_headerPhilipp Tomsich
The rockchip image generation was previously missing the ability to verify the generated header (and dump the image-type) without having to resort to hexdump or od. Experience in our testing has showed it to be very easy to get the rkspi and rksd images mixed up and the lab... so we add the necessary support to have dumpimage tell us what image type we're dealing with. This change set adds the verify_header and print_header capability to the rksd/rkspi image drivers (through shared code in rkcommon). As of now, we only support images fully that are not RC4-encoded for the SPL payload (i.e. header1 and payload). For RC4-encoded payloads, the outer header (header0) is checked, but no detection of whether this is a SD/MMC or SPI formatted payload takes place. The output of dumpsys now prints the image type (spl_hdr), whether it is a SD/MMC or SPI image, and the (padded) size of the image: $ ./tools/dumpimage -l ./spl.img Image Type: Rockchip RK33 (SD/MMC) boot image ^^^^^^ SD/MMC vs. SPI indication ^^^^ spl_hdr indicated by the image Data Size: 79872 bytes Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Acked-by: Simon Glass <sjg@chromium.org>
2017-05-10rockchip: mkimage: rewrite padding calculation for SD/MMC and SPI imagesPhilipp Tomsich
In (first) breaking and (then) fixing the rkspi tool, I realised that the calculation of the required padding (for the header-size and the 2K-in-every-4K SPI layout) was not as self-explainatory as it could have been. This change rewrites the code (using new, common functions in rkcommon.c) and adds verbose in-line comments to ensure that we won't fall into the same pit in the future... Tested on the RK3399 (with has a boot0-style payload) with SD/MMC and SPI. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Acked-by: Simon Glass <sjg@chromium.org>
2017-05-10rockchip: mkimage: rkspi: include the header sector in the SPI size calculationPhilipp Tomsich
Our earlier change broke the generation of SPI images, by excluding the 2K used for header0 from the size-calculation. This commit makes sure that these are included before calculating the required total size (including the padding from the 2K-from-every-4K conversion).

2017-04-04rockchip: mkimage: pad the header to 8-bytes (using a 'nop') for RK3399Philipp Tomsich
The RK3399 boot code (running as AArch64) poses a bit of a challenge for SPL image generation: * The BootROM will start execution right after the 4-byte header (at the odd instruction word loaded into SRAM at 0xff8c2004, with the 'RK33' boot magic residing at 0xff8c2000). * The default padding (during ELF generation) for AArch64 is 0x0, which is an illegal instruction and the .text section needs to be naturally aligned (someone might locate a 64bit constant relative to the section start and unaligned loads trigger a fault for all privileged modes of an ARMv8)... so we can't simply define the CONFIG_SPL_TEXT_BASE option to the odd address (0xff8c2004). * Finally, we don't want to change the values used for padding of the SPL .text section for all ARMv8 targets to the instruction word encoding 'nop', as this would affect all padding in this section and might hide errors that would otherwise quickly trigger an illegal insn exception. To deal with this situation, we modify the rkimage generation to - understand the fact that the RK3399 needs to pad the header to an 8 byte boundary using an AArch64 'nop' - the necessary logic to adjust the header_size (which controls the location where the payload is copied into the image) and to insert this padding (AArch64 insn words are always little-endian) into the image following the 4-byte header magic.

2017-04-04rockchip: mkimage: simplify start/size calculation for rc4_encodePhilipp Tomsich
The RC4 encoding works on full blocks, but the calculation of the starting offset and size are needlessly complicated by using a reference value known to be offset into a block by the size of the header and then correcting for the (hard-coded) size of the header (i.e. 4 bytes). We change this over to use the RK_SPL_HDR_START directly (which is known to be on a block boundary).

2017-03-16rockchip: mkimage: Allow encoding of loader code in spl imagesHeiko Stübner
Rockchip SoCs allow the spl code to be rc4-encoded, not only the image header, but only newer SoCs allow this encoding to be disabled. The rk3188 is not part of those and requires its boot code to be rc4-encoded with the regular key. So add the ability to do this encoding via a setting on a per-soc basis when building spl images.

2015-09-02rockchip: Add support for the SPI imageSimon Glass
The Rockchip boot ROM requires a particular file format for booting from SPI. It consists of a 512-byte header encoded with RC4, some padding and then up to 32KB of executable code in 2KB blocks, separated by 2KB empty blocks. Add support to mkimage so that an SPL image (u-boot-spl-dtb.bin) can be converted to this format. This allows booting from SPI flash on supported machines.
