Change to:
- reparam=3
- no-from-pointer
- no-stack-protector
- preferred-stack-boundary=2
- no-top-level-reorder
These options make the code a little smaller and faster
The header of recent Linux Kernels includes the size of the image, and
therefore is not needed to be passed to zboot. Still process the third
parameter (size of image) in the event that an older kernel is being loaded
Use TEXT_BASE rather than a hard-coded base address on x86 linker scripts.
This will allow any board to define its base link address without having
to modify the linker script
The GPIO 16 and 19 reconfiguration should be done once USB is initialized.
So moved the reconfiguration to the USB init function.

This patch changes the PPC4xx POST UART driver to use the common
NS16550 functions for receiving and sending. Additionally the
local function for SoC divisor setup are removed. Instead the
functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This
removes code duplication.
Also the common CONFIG_SYS_NS16550_COMx defines are now used
to describe the POST UART's.
And a compile breakage is fixed, introduced by a git merge of
the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to
"asm/ppc4xx.h". Fixed as well with this patch.

This patch fixes a bug in fdt_fixup_nor_flash_node() when the reg
property has multiple reg tuples, like:
reg = <0 0x00000000 0x04000000
0 0x04000000 0x04000000>;
In this case this function did not update the reg property correctly.

This patch brings the lwmon5 board support up-to-date. Here a
summary of the changes:
lwmon5 board port related:
- GPIO's changed to control the LSB transmitter
- Reset USB PHY's upon power-up
- Enable CAN upon power-up
- USB init error workaround (errata CHIP_6)
- EBC: Enable burstmode and modify the timings for the GDC memory
- EBC: Speed up NOR flash timings
lwmon5 board POST related:
- Add FPGA memory test
- Add GDC memory test
- DSP POST reworked
- SYSMON POST: Fix handling of negative temperatures
- Add output for sysmon1 POST

The OTP code does a little shuffling of arguments that aren't really
necessary, so use a local variable instead to fix build errors now

Building this board for parallel flash fills up the bss section and thus
fails to link, so bump up the monitor size a bit.

The current size used (256KiB) is smaller than the LDR created for
the bf548-ezkit, so 'run update' doesn't work correctly. So bump
up the size a bit by making this flexible per-board config.

Since we're no longer extracting the env from the target ELF file (since
upstream wouldn't take that change), we're back to the problem of cpu
defines not properly propagating to the env setup stage. So the embedded
env built by the host compiler doesn't match the one that is linked into
the u-boot env.

We need to use the Blackfin BootROM-specific OOB layout when we boot out
of NAND as that is what the on-chip ROM expects.
Also need to increase the monitor size a little to accommodate the extra
NAND code overhead.

The input sub command was missing from the help text, and it didn't show

The CONFIG_BFIN_CPU option is largely used in the build system, so move
it out of the board config.h and into the board config.mk. It'd be nice
to keep everything in the config.h, but the patch to extract that value
early was rejected.
