79df1208ee ns16550: change to allow 32 bit access to registers
If CONFIG_SYS_NS16550_MEM32 is defined then 32 bit memory
mapped access will be used to read/write the uart registers.

This is especially useful for SoC devices that implement 16550
compatible uarts but that have peripheral access width constraints.

025421eab4 fat: replace LINEAR_PREFETCH_SIZE with PREFETCH_BLOCKS
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
#define PREFETCH_BLOCKS instead of #define LINEAR_PREFETCH_SIZE.

40e219165b fat: root directory cluster only makes sense for FAT32
The root directory cluster field only exists in a FAT32 boot sector, so the
'root_cluster' variable in do_fat_read() contains garbage in case of FAT12/16.
Make it contain 0 instead as this is what is passed to get_vfatname() in that
case anyway.

60b36f0fc7 fat: cannot compare bytes and sectors
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.

ac4977719e fat: fix crash with big sector size

9e27e9dca1 FEC: Allow multiple FECes
This patch allows user to register multiple FEC controllers. To preserve
compatibility with older boards, the mxcfec_register() call is still in place.
To use multiple controllers, new macro is in place, the mxcfec_register_multi(),
which takes more arguments. The syntax is:

mxcfec_register_multi(bd, FEC ID, FEC PHY ID on the MII bus, base address);

To disable the fecmxc_register() compatibility stuff, define the macro
CONFIG_FEC_MXC_MULTI. This will remove the requirement for defining IMX_FEC_BASE
and CONFIG_FEC_MXC_PHYADDR.

correctly when divider computed from PERCLK.

Note: This constant is written to CBCDR register in
arch/arm/cpu/armv7/mx5/lowlevel_init.S, but it's written only once. The register
is accessed three more times in the file, with different values written to it
each time.
