hm...
It seems that the changes never reached upstream:
git://github.com/01org/edison-u-boot.git branch edison-v2014.04
this branch was implementing 'part info' sub-command which was useful to retrieve partition info.
the new repo:
git://github.com/edison-fw/u-boot.git branch acpi-v2020.04 does implement 'part number' but does not implement neither 'info' or 'block'.
I do not insist for you to take this patch, but I think it is useful (it is the simplest version which supports all needed functionality).
If you think the same, let me know. I can change name of the sub-command or implement this in a different way, if needed.
Thank you, Razvan

here is the implementation of the functions:
# function ota_conv_sizes # Convert a bytes size to a block size # input bytesize : size in bytes to convert # input blksize : size of a block in bytes # output num_blk : converted size in blocks setenv ota_conv_sizes 'setexpr num_blk $bytesize / $blksize ; setexpr mod_blk $bytesize % $blksize ; if itest $mod_blk > 0 ; then setexpr
num_blk
$num_blk + 1; fi;'
# function ota_mmc_write # Write a memory buffer to mmc drive # input floadaddr : address of buffer to write # input u_part_start : block start in mmc # input num_blk : number of block to write setenv ota_mmc_write 'if itest $ota_verbose == 1 ; then echo "mmc write ${floadaddr} ${u_part_start} ${num_blk};"; fi; mmc write $floadaddr $u_part_start $num_blk; ret=$?; if itest $ret != 0 ; then setenv ota_abort_reason "mmc write ${floadaddr} ${u_part_start} ${num_blk} failed"; setenv ota_abort 1; fi;'
the old u-boot version supported 'part info mmc 0:${u_part_num} u_part_start u_part_sz u_part_blksz;' to get the block size.
Old upstream U-Boot?
