- move common code to vidconsole_internal.h and console_core.c - unite probe functions - get rid of code duplications in switch across bpp values - extract common pixel fill logic in two functions one per horizontal and vertical filling - rearrange statements in put_xy* methods in unified way - replace types - uint*_t to u*
Signed-off-by: Dzmitry Sankouski dsankouski@gmail.com --- Changes for v2: none Changes for v3: none Changes for v4: - move common code to vidconsole_internal.h - unite probe functions Changes for v5: - move common functions to console-core.c file - remove static keyword from shared functions
