[PATCH] EDD: use EXTENDED READ command, add CONFIG_EDD_SKIP_MBR
Some controller BIOSes have problems with the legacy int13 fn02 READ
SECTORS command. int13 fn42 EXTENDED READ is used in preference by most
boot loaders today, so lets use that. If EXTENDED READ fails or isn't
supported, fall back to READ SECTORS.
This hopefully resolves the three reports of BIOSes which would either
long-pause (30+ seconds) or hang completely on the legacy READ SECTORS
command.
This also adds CONFIG_EDD_SKIP_MBR to eliminate reading the MBR on each
BIOS-presented disk, in case there are further problems in this area.
