Subject: cortex_a: remove broken dbgbase patchup code
X-Git-Tag: v0.5.0-rc1~113^2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=977df18f50f0f4d2310787787c03d83c2498da1a;p=openocd

cortex_a: remove broken dbgbase patchup code

the patchup code would get false positives when checking
whether a dbgbase had to be corrected.

The solution is to have autodetect default, with manual override
in scripts.
