9c52b24b00 patch #922836 by Jens: way faster disk writing, in assembler. The code is in, but yet disabled by #define PREFER_C_WRITING unless it's proven safe for all disks.

b646d4f278 Assembly code for copy_read_sectors() reworked: I've spread the ATA reads apart by filling independent instructions inbetween, this is also slightly faster because of no pipeline stall. Hopefully this fixes the problem Kargatron had with it.

cb570b9263 Assembler optimized copy_read_sectors() gives another speedup of factor 1.4 for aligned and 1.2 for misaligned. Including my previous change the file reading is now nearly twice as fast compared to when I started this. -> Less disk uptime, longer battery life.

88faf38ef7 Optimized the sector read loop as much as C allows. I measured an overall speed improvement for file reading of 12.5% for 16-bit aligned and 35% for misaligned. I took the rest of ata_read_sectors() out of IRAM, it's sufficient if only the copy loop stays there.

9f372f1f59 Cold start fixes: master_slave_select() now checks for BSY as well as RDY (since disks are BSY during powerup). Also, wait_for_bsy() looks at ATA_STATUS instead of ATA_ALT_STATUS, since the address of ATA_ALT_STATUS is not determined until later.
