arm: Remove support for unused s3c64xx

2013-04-12T05:55:08+00:00

Following the removal of the smdk6400 board, the s3c64xx SoC becomes unused, so
remove associated code. It will still be possible to restore it later from the
Git history if necessary.

arm: Remove unused relocate_code() parameters

2013-04-12T05:55:07+00:00

Commit e05e5de7fae5bec79617e113916dac6631251156 made the 2 1st parameters of
ARM's relocate_code() useless since it moved the code handling them to crt0.S.
So, drop these parameters.

arm: relocate_code() is no longer noreturn

2013-04-12T05:55:05+00:00

Commit e05e5de7fae5bec79617e113916dac6631251156 made ARM's relocate_code()
return to its caller, but it did not update its declaration accordingly.

Fixing this function declaration fixes dropped C code following calls to
relocate_code().

Adjust board_r.c for ppc

Introduce generic pre-relocation board_f.c

2013-03-15T20:13:59+00:00

This file handles common pre-relocation init for boards which use
the generic framework.

It starts up the console, DRAM, performs relocation and then jumps
to post-relocation init.

Update set_working_fdt_addr() to use setenv_addr()

2013-03-01T03:09:23+00:00

We might as well use this common function instead of repeating the same
code.

sandbox: Add un/map_sysmen() to deal with sandbox's ram_buf

2013-03-01T03:09:22+00:00

Sandbox doesn't actually provide U-Boot access to the machine's physical
memory. Instead it provides a RAM buffer of configurable size, and all
memory accesses are within that buffer. Sandbox memory starts at 0 and
is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer
might produce unpredictable results in the event of an error, and would
expose the host machine's memory architecture to the sandbox U-Boot.

Most U-Boot functions assume that they can just access memory at given
address. For sandbox this is not true.

Add a map_sysmem() call which converts a U-Boot address to a system
address. In most cases this is a NOP, but for sandbox it returns a
pointer to that memory inside the RAM buffer.

To get a U-Boot feature to work correctly within sandbox, you should call
map_sysmem() to get a pointer to the address, and then use that address for
any U-Boot memory accesses.

Update print_buffer() to use const

2013-03-01T03:09:21+00:00

The buffer cannot be changed by this function, so change the buffer
pointer to a const. This allows callers with const pointer to use the
function without a cast.

Add option to display customised memory information

2013-01-10T21:22:12+00:00

Some boards want to report more than just memory size. For example, it
might be useful to display the memory type (DDR2, DDR3) or manufacturer.

Add a weak function to support this requirement, accessed through a new
'meminfo' command.

Any example of the DRAM: output is below, just for illustration:

SMDK5250 # meminfo
DRAM:  2 GiB Elpida DDR3 @ 800MHz

arm: move C runtime setup code in crt0.S

2013-01-08T21:14:50+00:00

Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().

Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).

Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant
maintainers and custodians are cc:ed.
