Subject: target: add -dbgbase option to target configuration
X-Git-Tag: v0.5.0-rc1~118
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=b75bdb7b0428add602c2e4beb7e059da5d4a6c95;p=openocd

target: add -dbgbase option to target configuration

Really a Cortex-A specific option, but there is no
system in place to support target specific options
currently and there has been no need for such a system
until now.
