fatload failes on 2G file

[Oliver Graute]

Hello,

I try to load a 2GB file from SD-Card to write it later to eMMC. But there
is some limitation resulting in this error from fs_read_lmb_check():

** Reading file would overwrite reserved memory **

=> fatload mmc 2:0 ${loadaddr} 1G_file.bin
1073741824 bytes read in 45722 ms (22.4 MiB/s)

=> fatload mmc 2:0 ${loadaddr} 2G_file.bin
** Reading file would overwrite reserved memory **

I have a board with 8GB RAM on two Banks (2GB + 6GB) where is these
limitation coming from?

Best Regards,

Oliver
