The erratum NMG_LBC103 is LBIU3 in MPC8548 errata document.
Any local bus transaction may fail during LBIU resynchronization
process when the clock divider [CLKDIV] is changing. Ensure there
is no transaction on the local bus for at least 100 microseconds
after changing clock divider LCRR[CLKDIV].
Refer to the erratum LBIU3 of mpc8548.

Erratum NMG_DDR120 (DDR19 in MPC8548 errata document) applies to some
early version silicons. The default settings of the DDR IO receiver
biasing may not work at cold temperature. When a failure occurs,
a DDR input latches an incorrect value. The workaround will set the
receiver to an acceptable bias point.

Pre u-boot Flow:
1. User loads the u-boot image in flash
2. PBL/Configuration word is used to create LAW for Flash at 0xc0000000
(Please note that ISBC expects all these addresses, images to be
validated, entry point etc within 0 - 3.5G range)
3. ISBC validates the u-boot image, and passes control to u-boot
at 0xcffffffc.
Changes in u-boot:
1. Temporarily map CONFIG_SYS_MONITOR_BASE to the 1M
CONFIG_SYS_PBI_FLASH_WINDOW in AS=1.
(The CONFIG_SYS_PBI_FLASH_WINDOW is the address map for the flash
created by PBL/configuration word within 0 - 3.5G memory range. The
u-boot image at this address has been validated by ISBC code)
2. Remove TLB entries for 0 - 3.5G created by ISBC code
3. Remove the LAW entry for the CONFIG_SYS_PBI_FLASH_WINDOW created by
PBL/configuration word after switch to AS = 1

Currently in do_fat_read() when reading FAT sectors, we have to divide down
LINEAR_PREFETCH_SIZE by the sector size, whereas it's defined as 2 sectors
worth of bytes. In order to avoid redundant multiplication/division, introduce

The root directory cluster field only exists in a FAT32 boot sector, so the

Make it contain 0 instead as this is what is passed to get_vfatname() in that
case anyway.

The code multiples the FAT size in sectors by the sector size and then tries to
compare that to the number of sectors in the 'getsize' variable. While fixing
this, also change the initial value of 'getsize' as the division of FATBUFSIZE
by the sector size gets us FATBUFBLOCKS.
