u-boot.bin can be loaded at any 4-byte aligned memory location and directly
'jumped' to using the 'go' command using the load address as the start
address. Doing so performs a 'warm boot' which skips memory initialisation
and other low-level initialisations, relocates U-Boot to upper memory and
starts U-Boot in RAM as per normal 'cold boot'
Provides a small speed increase and prepares for fully relocatable image.
Downside is the TEXT_BASE, bss, load address etc must ALL be aligned on a
a 4-byte boundary which is not such a terrible restriction as everything
is already 4-byte aligned anyway
By reserving space for the Global Data immediately below the stack during
assembly level initialisation, the C declaration of the static global data
can be removed, along with the 'RAM Bootstrap' function. This results in
cleaner code, and the ability to pass boot-up flags from assembler into C
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 patch adds support for TTECH vision2 board.
The board has 512MB RAM, SDHC slot and 4MB SPI
device from StMicron.

The spansion_erase currently only works when the sector size is 64KB.
cmd[1] should contain the higher 8 bit of the 24 bit address of the
sector to be erased. Currently it is holding the sector index to be
erased which happens to be the same thing when the sector size is
64KB.

This patch adds a new config parameter for adjusting the calculation of
hash table size when importing a buffer.
When importing a extremely small buffer (e.g. the default_environment)
the old calculation generated a hash table which could hold at most the
buffer content but no more entires.
The new calculation add a fixed number of entries to the result to fit
better for small import buffers. This amount may be configured by the
user in board file to adjust the behaviour.

The current ELF loading function does a lot of work above and beyond a
simple "loading". It ignores the real load addresses and loads things
into their virtual (runtime) address. This is undesirable when we just
want it to load an ELF and let the ELF do the actual C runtime init.
So add a command line option to let people choose to load via either the
program or section headers. I'd prefer to have program header loading
be the default, but this would break historical behavior, so I'll leave
section header loading as the norm.

There are some cases where "make depend" would always run when
entering a directory. This happened when both the $(SRCS) and
$(HOSTSRCS) lists were empty (which is for example typical for the
examples/api/ directory). Avoid this by making sure that a ".depend"
file gets always created, even if empty.

When disabled the PIT runs until it reaches the CPIV value.
The Linux PIT driver stops the PIT and waits until it stopped. This can
take over 100ms. Simply stopping in u-boot isn't sufficient as the PIT
will still be running when Linux is waiting until it stopped.
So, we stop it in u-boot by setting the compare value to a value slightly
greater than the current running counter to make the PIT stopped in short
time.
