Subject: powerpc: mpc85xx: Define linker sections in ascending order
X-Git-Tag: v2022.07~75^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1245c6e2582cb67db2a84e60a61cfe5a8d77e068;p=platform%2Fkernel%2Fu-boot.git

powerpc: mpc85xx: Define linker sections in ascending order

It is too confusing if sections are defined in non-ascending order.

Also linker has to go backward and then again forward when generating final
binary.

To make future changes easier, define all linker sections in ascending
order.
