Hi Marek,
your patch "fs: fat: Fix mkcksum() function parameters" (sha1: ff04f6d1224d8952b566b8671222151495883073) is causing the problem on xilinx zynq platform.
Here is what I get as output when patch is in the tree. You see that all files are there twice and more. zynq-uboot> fatls mmc 0 4045655 download.bit 4045655 download.bit 2729968 zimage 2729968 zimage 5256 zynq-zc702-adv7511.dtb 5256 zynq-z~1.dtb ubuntu/ ubuntu/ 4380524 boot.bin-14.1 4380524 bootbi~1.1 4359340 boot.bin-14.3 4359340 bootbi~1.3 4359340 boot.bin-latest 4359340 boot~1.bin 68044 output.bin 68044 output.bin 329044 boot.bin 329044 boot.bin zc702/ zc702/

When I revert your patch I get the correct output zynq-uboot> fatls mmc 0 4045655 download.bit 2729968 zimage 5256 zynq-zc702-adv7511.dtb ubuntu/ 4380524 boot.bin-14.1 4359340 boot.bin-14.3 4359340 boot.bin-latest 68044 output.bin 329044 boot.bin zc702/

It is tested on mmc driver and here is information about SD card I use. VFAT support is also enabled.

I didn't look at background just bisect which patch introduced this problem. Any input from you will be useful.
Thanks, Michal
