This adds flash support for the SoC. BUG=chrome-os-partner:44745 BRANCH=none TEST=manual Pick an unused section of flash and use the flasherase and flashwrite commands to test it. The flashwrite command fills a buffer with bytes, counting up (0x00, 0x01, 0x02, 0x03, ...), then writes that buffer to the address given. Note that the "md" command uses the absolute address, while the flash commands use the offset address within the flash memory. For example: Test bank 0: > md 0x7b000 16 0007B000: 00000000 00000000 00000000 00000000 0007B010: 00000000 00000000 00000000 00000000 0007B020: 00000000 00000000 00000000 00000000 0007B030: 00000000 00000000 00000000 00000000 > flasherase 0x3b000 0x800 Erasing 2048 bytes at 0x3b000... > md 0x7b000 16 0007B000: ffffffff ffffffff ffffffff ffffffff 0007B010: ffffffff ffffffff ffffffff ffffffff 0007B020: ffffffff ffffffff ffffffff ffffffff 0007B030: ffffffff ffffffff ffffffff ffffffff > > flashwrite 0x3b000 0x800 Writing 2048 bytes to 0x3b000... > md 0x7b000 16 0007B000: 03020100 07060504 0b0a0908 0f0e0d0c 0007B010: 13121110 17161514 1b1a1918 1f1e1d1c 0007B020: 23222120 27262524 2b2a2928 2f2e2d2c 0007B030: 33323130 37363534 3b3a3938 3f3e3d3c > md .b 0x7b000 16 0007B000: 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f Test bank 1: > md 0xbb000 16 000BB000: ffffffff ffffffff ffffffff ffffffff 000BB010: ffffffff ffffffff ffffffff ffffffff 000BB020: ffffffff ffffffff ffffffff ffffffff 000BB030: ffffffff ffffffff ffffffff ffffffff > flasherase 0x7b000 0x800 Erasing 2048 bytes at 0x7b000... > md 0xbb000 16 000BB000: ffffffff ffffffff ffffffff ffffffff 000BB010: ffffffff ffffffff ffffffff ffffffff 000BB020: ffffffff ffffffff ffffffff ffffffff 000BB030: ffffffff ffffffff ffffffff ffffffff > flashwrite 0x7b000 0x800 Writing 2048 bytes to 0x7b000... > md 0xbb000 16 000BB000: 03020100 07060504 0b0a0908 0f0e0d0c 000BB010: 13121110 17161514 1b1a1918 1f1e1d1c 000BB020: 23222120 27262524 2b2a2928 2f2e2d2c 000BB030: 33323130 37363534 3b3a3938 3f3e3d3c > md .b 0xbb000 16 000BB000: 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f > Change-Id: I956e813871949faed8d85ad9e46bdc64dee1a9e9 Signed-off-by: Bill Richardson <wfrichar@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/299757
