Subject: tcl/target|board: move common AR9331 code to atheros_ar9331.cfg
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=dcf977c89a24b02fd8200af633be1fdd3add4ae7;p=openocd

tcl/target|board: move common AR9331 code to atheros_ar9331.cfg

The ar9331_25mhz_pll_init and ar9331_ddr1_init routines
can be used not only for TP-Link MR3020 board,
so move them to the common atheros_ar9331.cfg file.
