[ Upstream commit beefaba1978c04ea2950d34236f58fe6cf6a7f58 ]
dummycon fails to build on ARM/footbridge when the VGA console is disabled, since I got the dependencies slightly wrong in a previous patch:
drivers/video/console/dummycon.c: In function 'dummycon_init': drivers/video/console/dummycon.c:27:25: error: 'CONFIG_DUMMY_CONSOLE_COLUMNS' undeclared (first use in this function); did you mean 'CONFIG_DUMMY_CONSOLE'? 27 | #define DUMMY_COLUMNS CONFIG_DUMMY_CONSOLE_COLUMNS drivers/video/console/dummycon.c:28:25: error: 'CONFIG_DUMMY_CONSOLE_ROWS' undeclared (first use in this function); did you mean 'CONFIG_DUMMY_CONSOLE'? 28 | #define DUMMY_ROWS CONFIG_DUMMY_CONSOLE_ROWS
This only showed up after many thousand randconfig builds on Arm, and doesn't matter in practice, but should still be fixed. Address it by using the default row/columns on footbridge after all in that corner case.
