Subject: nandbcb: nand support for i.MX8MP
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=42a49754e2c68694c8c4600c203430dd2625a7d6;p=u-boot.git

nandbcb: nand support for i.MX8MP

Add NAND boot support for i.MX8MP by adding i.MX8MP in nandbcb support
list, reading boot_search_count from fuse.

i.MX8MN NAND boot is same as i.MX8MP, fix some issues as well.
