X-Git-Tag: v2019.07-rc2~20^2~17
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1b1d8c19f5b4b799232eee70e8916cd2491872ec;p=oweals%2Fu-boot.git

spl: fix linker size check off-by-one errors

This fixes SPL linker script size checks for 3 lds files where the size
checks were implemented as "x < YYY_MAX_SIZE".

Fix the size checks to be "x <= YYY_MAX_SIZE" instead.
