That doesn't work with bootpart=1:2 (that\nis defined in include/environment/ti/boot.h). To fix Linux boot we may\neither:\n\n 1. Change bootpart to be 1:1\n 2. Or add preceding partition, so that rootfs is actually 1:2\n\nSecond choice seems more reasonable, as DFU is already using similar\npartition table and can rely on bootpart to be 1:2.\n\nThis patch adds \"bootloader\" partition. So now eMMC layout for Linux\nboot looks like this:\n\noffset content size partition\n(KiB) (KiB)", "diff": "=======================================================================\n\n0 +--------------------------------+\n | MBR/GPT header | 128 -\n128 +--------------------------------+\n | MLO | 256 -\n384 +--------------------------------+\n | u-boot.img | 1792 bootloader\n2176 +--------------------------------+\n | //////////// hole //////////// | 256 -\n2432 +--------------------------------+\n | U-Boot environment | 128 -\n2560 +--------------------------------+\n | U-Boot environment (redundant) | 128 -\n2688 +--------------------------------+\n | rootfs | remaining rootfs\nend +--------------------------------+\n\n=======================================================================\n\nGuard hole appears because U-Boot environment offset was calculated for\nAndroid partition table, which has two additional partitions in place of\nthat hole (\"environment\" and \"misc\" partitions).\n\nThis patch also changes rootfs offset from 2 MiB further to 2688 KiB,\nso that there won't be any collisions with U-Boot environment when we\nflash rootfs.\n\nSigned-off-by: Sam Protsenko <semen.protsenko@linaro.org>\n---\n include/configs/dra7xx_evm.h | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)\n\ndiff --git a/include/configs/dra7xx_evm.h b/include/configs/dra7xx_evm.h\nindex 6c0fc35d3a..1555fc1b50 100644\n--- a/include/configs/dra7xx_evm.h\n+++ b/include/configs/dra7xx_evm.h\n@@ -51,7 +51,8 @@\n #define PARTS_DEFAULT \\\n \t/* Linux partitions */ \\\n \t\"uuid_disk=${uuid_gpt_disk};\" \\\n-\t\"name=rootfs,start=2MiB,size=-,uuid=${uuid_gpt_rootfs}\\0\" \\\n+\t\"name=bootloader,start=384K,size=1792K,uuid=${uuid_gpt_bootloader};\" \\\n+\t\"name=rootfs,start=2688K,size=-,uuid=${uuid_gpt_rootfs}\\0\" \\\n \t/* Android partitions */ \\\n \t\"partitions_android=\" \\\n \t\"uuid_disk=${uuid_gpt_disk};\" \\\n", "prefixes": [ "U-Boot", "2/4" ] }
