On some machines using a specific hardware for console screen output, the update of the pixel frame buffer does not work correctly when using command line edition. This may be due to a memory cache bug in the machine on which the problem has been found, but an other solution is possible. This patch proposes to avoid touching directly the pixel frame buffer and to rebuild each character using the standard putc() function on command line edition. The resulting code is smaller and not obviously slower (no read access to the pixel frame buffer). Tested on a Cubox (ARM Marvell Dove 88AP510 SoC).
