There are some braindead designs (e.g. Variscite SOMs) that have both eMMC and NAND on board and only able to boot off of NAND. Android FS layout uses insane number of partitions so it would be logical to put some of those onto NAND while keeping others on eMMC. However at present time the target device for "flash" command is a compile-time option that only allows writing to one device. Is anybody working on this currently? I don't want to re-invent the wheel. I will come up with initial RFC if nobody work on this...
While retaining the storage abstraction feature implemented in U-Boot, this series updates the fastboot sparse image handling by (1) fixing broken code, (2) resync'ing with the upstream code, and (3) improving performance when writing CHUNK_TYPE_FILL Changes in v2: - series rebased onto v2016.07-rc1 Steve Rae (5): fastboot: sparse: remove session-id logic fastboot: sparse: resync common/image-sparse.c (part 1) fastboot: sparse: resync common/image-sparse.c (part 2) fastboot: sparse: implement reserve() fastboot: sparse: improve CHUNK_TYPE_FILL write performance common/fb_mmc.c | 79 +++---- common/fb_nand.c | 106 +++++---- common/image-sparse.c | 478 +++++++++++++++------------------------- drivers/usb/gadget/f_fastboot.c | 47 ++-- include/fastboot.h | 4 +- include/fb_mmc.h | 7 +- include/fb_nand.h | 7 +- include/image-sparse.h | 29 ++- 8 files changed, 312 insertions(+), 445 deletions(-) -- 1.8.5 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
