AHCLKR/UART1_RTS/GP0[11] pin needs to be configured for
MMC and NOR to work on Rev.3 EVM. When GP0[11] is low,
the SD0 interface will not work, but NOR flash will. When
GP0[11] is high, SD0 will work but NOR flash will not.

Earlier "mmc rescan" command from U-Boot prompt would always
return ZERO, hence it was not possible to use this command to
know whether the MMC/SD card is present in the slot or not.
This patch corrects this issue.
In the process, modify the bootargs to include a check to find
whether the MMC/SD card is present or not.

Added Multi-Block Read support for MMC. Modified existing multi-block write
to limit the maximum number of blocks per transfer. This feature is enabled
with CONFIG_MMC_MBLOCK option. A new member is added in the mmc structure
for the host controllers to specify the maximum number of blocks it supports.
If the feature is disabled all read/write transfers are single-block.

Starting from kernel 2.6.24 'rootwait' can be used to wait for
the rootdevice to become ready, this is preferred over choosing
a random delay.
In the case of da8xx/omap-l1xx the delay is dependant on the MMC
card present and can take more than 10 seconds in some cases.

Davinci: davinci_nand.c performance enhancments
Introduces various optimisations that approximately triple the
read data rate from NAND when run on da830evm.
Most of these optimisations depend on the endianess of the machine
and most of them are very similar to optimisations already present
in the Linux Kernel.

Davinci: NAND enable ECC even when not in NAND boot mode
Davinci: NAND enable ECC even when not in NAND boot mode
On Davinci platforms, the default NAND device is enabled (for ECC)
in low level boot code when NAND boot mode is used. If booting in
another mode, NAND ECC is not enabled. The driver should make
sure ECC is enabled regardless of boot mode if NAND is configured
in U-Boot.

Davinci: Table driven pinmux configuration
Davinci: Table driven pinmux configuration
Add code to allow pinmux_config tables to be grouped and configured
as a single resource. This removes multiple calls to the pinmux
configuration code from board_init and allows pinmuxes to be
individually configured and added by data manipulation only.
All related #ifdefs can the be removed from board_init code and
since the compiler optimises away statics, #ifdefs can be reduced in
the data definitions as well.

The gd->cpu pointer is set to an address located in flash when the
probecpu() function is called while U-Boot is executing from flash.
This pointer needs to be updated to point to an address in RAM after
relocation has occurred otherwise Linux may not be able to boot due to
"fdt board" crashing if flash has been erased or changed.
This bug was introduced in commit
a0e2066f392782730f0398095e583c87812d97f2.

Commit c7190f02 (retain POR values of non-configured ACR, SPCR, SCCR,
and LCRR bitfields) moved the LCRR assignment to after relocation
to RAM because of the potential problem with changing the local bus
clock while executing from flash.
This change unfortunately adversely affects the boot time, as running
all code up to cpu_init_r can cause significant slowdown.
E.G. on a 8347 board a bootup time increase of ~600ms has been observed:
0.020 CPU: e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz
0.168 RS: 232
0.172 I2C: ready
0.176 DRAM: 64 MB
1.236 FLASH: 32 MB
Versus:
0.016 CPU: e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz
0.092 RS: 232
0.092 I2C: ready
0.096 DRAM: 64 MB
0.644 FLASH: 32 MB
So far no boards have needed the late LCRR setup, so simply revert it
for now - If it is needed at a later time, those boards can either do
their own final LCRR setup in board code (E.G. in board_early_init_r),
or we can introduce a CONFIG_SYS_LCRR_LATE config option to only do
the setup in cpu_init_r.
