Whilst U-boot does not require this itself, Linux currently relies upon
it having been muxed and enabled by the bootloader. Thus in order to
preserve compatibility with current kernels before a fix is merged in
Linux we will enable the SERIRQ interrupt and mux it to its pin.
Without doing this current kernels will never receive serial port
interrupts and the end result is typically that userland appears to
hang.

|OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |GPMC |S/W BCH library |

Current implementation limits the BCH8_CODE_HW only for AM33xx device family.
(using CONFIG_AM33XX). However, other SoC families (like TI81xx) also have
ELM hardware module, and can support ECC error detection using ELM.
This patch
- removes CONFIG_AM33xx
Thus this driver can be reused by all devices having ELM h/w engine.
- adds omap_select_ecc_scheme()
A common function to handle ecc-scheme related configurations. This
can be used both during device-probe and via user-space u-boot commads
to change ecc-scheme. During device probe ecc-scheme is selected based
on CONFIG_NAND_OMAP_ELM or CONFIG_NAND_OMAP_BCH8
- enables CONFIG_BCH

The physical base address of the NOR flash is 0x1e000000
on the Malta boards. The hardware also maps the first 4MiB
of the flash into the 0x1fc00000-0x1fffffff range.
Currently, U-Boot uses the mapped address to access the
flash, which does not work in recent qemu versions.
Since commit a427338b222b43197c2776cbc996936df0302f51
(mips_malta: correct reading MIPS revision at 0x1fc00010)
writing to the mapped address space causes a CPU exception.
Due to the exception, U-Boot hangs during boot when it tries
to detect the CFI flash chip.
Use the correct physical address for the MALTA_FLASH_BASE
constant to fix the problem. In order to avoid relocation
problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE
constants.
The change makes it possible to start U-Boot on a Malta
board emulated with Qemu 1.6.1 and 1.7.0-rc0. It also
works on older versions (tested with 1.1.1, 1.2.2, 1.4.2,
1.5.3).

Makefile conflicts are due to additions/removals of

This also applies to two files which are not listed

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM

Resolution is to convert as this icludes removal of

include/configs/pdnb3.h is due to a removal on ARM side.

This patch adds support for running on Malta boards using coreFPGA6
core cards, including support for the msc01 system controller used
with them. The system controller is detected at runtime allowing one
U-boot binary to run on a Malta with either.
Due to the PCI I/O base differing between Maltas using gt64120 & msc01
system controllers, the UART setup is modified slightly. A second UART
is added so that there is one pointing at the correct address for each
system controller. The Malta board then defines its own
default_serial_console function to select the correct one at runtime.
The incorrect UART will simply not function.
Tested on:
- A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both
with and without an L2 cache.
- QEMU.

For boards such as the MIPS Malta with an FPGA core card it is desirable
to be able to detect the L1 cache sizes at runtime, since they are not
dependant upon the board but on the FPGA bitstream in use. This patch
performs that detection when the CONFIG_SYS_[DI]CACHE_SIZE macros are
not defined by the board configuration. In cases where the sizes are
detected this patch also removes the restriction that the I-cache &
D-cache line sizes must be the same, as this is not necessarily true.
If the cache sizes are defined by a configuration then they will be
hardcoded as before, so this patch will not add overhead to such
boards.

The change from 0x64656465 to 0x64646464 is to remove the weak pull
enabled on DQS, nDQS lines. This pulls the differential signals in the
same direction which is not intended. So disabling the weak pulls improves
signal integrity.
On the uEVM there are 4 DDR3 devices. The VREF for 2 of the devices is powered by
the OMAP's VREF_CA_OUT pins. The VREF on the other 2 devices is powered by the OMAP's
VREF_DQ_OUT pins. So the net effect here is that only half of the DDR3 devices were being
supplied a VREF! This was clearly a mistake. The second change improves the robustness of
the interface and was specifically seen to cure corruption observed at high temperatures
on some boards.
With the above two changes better memory stability was observed with extended
temperature ranges around 100C.
