Subject: powerpc: mpc85xx: Rename _start_e500 symbol to _start
X-Git-Tag: v2022.07~75^2~44
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=de14a5a95c14b0a5349c430ea35b8b07975f7ce5;p=platform%2Fkernel%2Fu-boot.git

powerpc: mpc85xx: Rename _start_e500 symbol to _start

The real entry point is _start_e500. There is no _start symbol at all. So
rename _start_e500 to _start for convension that _start symbol is used as
entry point.
