mmu_setup() was originally written in U-Boot to utilize board-specific

RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.
However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.
This also has the pleasant side-effect of fixing the coreboot tables
to not clobber ramstage code...

Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled

For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

Summary:
Isolate CBFS underlying I/O to board/arch-specific implementations as
"media stream", to allow loading and booting romstage on non-x86.
CBFS functions now all take a new "media source" parameter; use
CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
API Changes:
cbfs_find => cbfs_get_file.
cbfs_find_file => cbfs_get_file_content.
cbfs_get_file => cbfs_get_file_content with correct type.
CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.
To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media". To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.
Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
struct cbfs_file *entry = cbfs_get_file(media, name);
void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);
Test results:
- Verified to work on x86/qemu.
- Compiles on ARM, and follow up commit will provide working SPI driver.

This makes extra step (prefix 0x, and then generate another temp file) in build

The previous incarnation did not use all of mmu_setup, which meant
we did not carefully disable things before (possibly) changing them.
This code is tested and works, and it's a bit of a simplification.

There are still many commented out references to gd-> and bd-> which
we'll fix once we're happy with the replacements.

This just removes unused code. If for some reason we don't want to
initialize cache, then the CPU or mainboard specific init routines
don't need to call these.

commit 23c046b6f1 Author: Nico Huber <nico.huber@secunet.com> Date: Mon Sep 24 10:48:43 2012 +0200
Fix reading of number of interrupts for IO-APICs
The number read from the io-apic register represents the index of the
highest interrupt redirection entry, i.e. the number of interrupts
minus one.

This patch does a few things to get us into romstage:
- Add romstage as a stage (a later patch adds it as a binary, which
is probably wrong). The Makefile magic is complex enough that we
let it build the XIP file for now, but we no longer use it.
- Replace findstage with loadstage. Loadstage will find a stage,
load the code to memory, and zero the remaining part of memory.
Now we can link the romstage to go anywhere!
- Eliminate magic offsets from code/ldscripts and centralize Kconfig
variables in src/cpu/samsung/exynos5250/Kconfig.
- Tidy up code and serial output

This adds a wrapper around main() in romstage which is compiled using
-marm. This assumes that the bootblock branches to romstage in ARM
mode.
The long-term idea is to enforce ABI compatibility when handing off to
the next stage by using shims which are which are compiled in a pre-
determiend manner and leave the main portions of each stage up to
whatever the compiler wants. So it will eventually look like this:
1. bootblock_main (ARM/Thumb)
2. bootblock_exit (ARM)
3. romstage_entry (ARM)
4. romstage_main (ARM/Thumb)

This is the bloated Snow bootblock which includes:
- SPI driver
- UART, including requisite I2C, Maxim PMIC, and clock config code.
- Adjustments for magic offsets (id section, stack pointer address)
This is just a temporary solution until we have romstage loading.
Once that happens, we'll rip out all but the code necessary for
copying SPI ROM content into SRAM.

Our earlier attempt was jumping straight from asm to the old u-boot
board_init_f in lowlevel_init_c.c. We are getting ready to transition
to using a real bootblock for ARM, so add romstage.c to the files
compiled and we'll make main() our entry point.
This also updates romstage.ld to place main() (*(.text.startup)) at
the beginning of romstage.

This replaces hard-coded bootblock offsets using the new scheme.
The assembler will place the initial branch instruction after BL1,
skip 2 aligned chunks, and place the remaining bootblock code after.
It will also leave an anchor string, currently 0xdeadbeef which
cbfstool will find. Once found, cbfstool will place the master CBFS
header at the next aligned offset.
Here is how it looks:
0x0000 |--------------|
| BL1 |
0x2000 |--------------|
| branch |
0x2000 + align |--------------|
| CBFS header |
0x2000 + align * 2 |--------------|
| bootblock |
|--------------|
TODO: The option for alignment passed into cbfstool has always been
64. Can we set it to 16 instead?

This lays out the groundwork for using a proper bootblock on ARM.
Currently we bypass the bootblock entirely and go straight to
romstage. However we want to utilize CBFS to maximize flexibility
of placing code without relying on a lot of magic numbers which
will break depending on the SoC in use.
