* sunxi: (mksunxiboot) signature to indicate "sunxi" SPL variantBernhard Nortmann2015-09-29-0/+4
| | | | | | | | | | | | | | | | | | | | | | This patch follows up on a discussion of ways to improve support for the sunxi FEL ("USB boot") mechanism, especially with regard to boot scripts, see: https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ The idea is to convert the (currently unused) "pad" bytes in the SPL header into an area where data can be passed to U-Boot. To do this safely, we have to make sure that we're actually using our "sunxi" flavor of the SPL, and not the Allwinner boot0. The modified mksunxiboot introduces a special signature to the SPL header in place of the "pub_head_size" field. This can be used to reliably distinguish between compatible versions of sunxi SPL and anything else (older variants or Allwinner's boot0).

* sunxi: move SPL-related definitions to platform-specific includeBernhard Nortmann2015-09-29-16/+1
| | | | | | | | | | | | | The sunxi platform currently doesn't seem to make any use of the asm/arch-sunxi/spl.h file. This patch moves some declarations from tools/mksunxiboot.c into it. This enables us to reuse those definitions when extending the sunxi board code (boards/sunxi/boards.c).

* sunxi: Ensure that 'mksunxiboot' tool produces deterministic outputSiarhei Siamashka2015-09-10-1/+1
| | | | | | | | | | | | | | | | | | | | Currently some uninitialized padding bytes are written to the output file, as can be confirmed with valgrind: $ valgrind tools/mksunxiboot spl/u-boot-spl.bin spl/sunxi-spl.bin ==5581== Syscall param write(buf) points to uninitialised byte(s) ==5581== at 0x4F0F940: __write_nocancel (in /lib64/libc-2.20.so) ==5581== by 0x400839: main (in /tmp/u-boot/tools/mksunxiboot) ==5581== Address 0xffeff5d3c is on thread 1's stack ==5581== in frame #1, created by main (???) This patch fixes the problem by clearing the whole structure instead of just a portion of it.

* sunxi/nand: change BLOCK_SIZE in mksunxiboot to match NAND block sizeDaniel Kochmański2015-05-29-1/+7
| | | | | | | | | | | This change is necessary to calculate correct checksum for NAND boot. Works both for MMC and NAND. Without it BROM rejects boot image as invalid (bad checksum). (Changes block size from 0x200 to 0x2000).

| | | | | | | | | | | | | of 4 We should not be aligning the amount of bytes which we try to read from the disk, this leads to trying to read more bytes then there are which fails. file_size is already aligned to BLOCK_SIZE before being stored in img.header.length, so there is no need for load_size at all.
