2010-10-11	63690cc Browse files » Don't try to guess the size of a disk if its size value is already given ... Guessing the size of an attached harddisk (access via x86 BIOS) was needed due to the fact, barebox can't query this information from the BIOS easily. But with the SD/MMC cards, there will be a second user of the generic disk handling routines. And with this media it is very easy to know its size. This patch provides a workaround to keep the guessing feature if the size of the registered disk is 0. If it is not 0, the given value will be used instead. Note: This is in preparation to add MCI card support, which can be handled like a disk drive.

	5340589 Browse files » Don't use a sector buffer on stack ... Using a temp. buffer for a disk sector on the stack, seems not work. Doing so lets the system run crazy (the stack seems to be destroyd). Don't know the correct stack handling on ARM, but (IMHO) I also can exclude any writing across the buffer boundaries. Using a temp. buffer via malloc() runs also on ARM. Note: This patch was required to add MCI card support, which can be handled like a disk drive.
