This updates DRAM usage for Kirby so that we can actually

- The chips on Kirby have 16 row address lines.
- CONFIG_DRAM_SIZE_MB should be 3584 (4096-512).
- We use 2 DMC channels on Kirby (each with 2GB).

This changes the number of chip selects that we configure from 2 to 1.
On current setups with (x16 memory 4Gbit chips) that means that we're
at 2GByte.
Technically we should add a second setting in the ares_ddr3_timings
and select between the two of the based on board strappings. That
would make the CONFIG_RUN_TIME_BANK_NUMBER would work properly. I've
changed the ddr3_mem_ctrl_init() so it should handle that, but I'm not
actually doing the board strapping read right now.
This change means that accesses to 0xA0000000 - 0xFFFFFFFF on 2G
systems will no longer put the system in a messed up state (leading to
a hang). It also prevents some of the weird boot behavior that we've
seen that comes and goes depending on U-Boot alignment. See

This patch makes the EHCI driver work on ARM platforms which usually do
not support automatic cache snooping. It uses the new DMA memory
mechanism (which needs to be correctly set up in the Coreboot mainboard

cache-coherent memory, and cleans/invalidates the externally supplied
transfer buffers in Bulk and Control functions with explicit calls as
necessary.

This patch adds a mechanism to set aside a region of cache-coherent
(i.e. usually uncached) virtual memory, which can be used to communicate
with DMA devices without automatic cache snooping (common on ARM)
without the need of explicit flush/invalidation instructions in the
driver code.
This works by setting aside said region in the (board-specific) page
table setup, as exemplary done in this patch for the Snow, Pit and Kirby
boards. It uses a new mechanism for adding board-specific Coreboot table
entries to describe this region in an entry with the LB_DMA tag.
Libpayload's memory allocator is enhanced to be able to operate on
distinct types/regions of memory. It provides dma_malloc() and
dma_memalign() functions for use in drivers, which by default just
operate on the same heap as their traditional counterparts. However, if
the Coreboot table parsing code finds a CB_DMA section, further requests
through the dma_xxx() functions will return memory from the region
described therein instead.

This patch intends to remove all code which enables hardware read
leveling. We need to disable h/w read leveling because new ASV table
is merged in kernel (which is based on the new characterization
condition) and new characterization environment has h/w read leveling
disabled, so we should also disable this. Also, disabling h/w read
leveling improves the MIF LVcc value (LVcc value is the value at which
DDR will fail to work properly), improve LVcc means we have enough
voltage margin for MIF. When h/w leveling is enabled, we have almost
zero volatge margin.

* On snow there's a bypass around FET4 which effectively eliminates

Turning on FET4 doesn't hurt though and is technically correct.
* On pit the EC turns on FET4 on cold bootup.
On pit we run into a problem if the kernel turns off FET4 like in

Apparently the IROM doesn't like data caches... the recently added
dcache-in-bootblock makes A-A booting fail, and flushes/invalidations
alone don't seem to fix it. It's pretty fast anyway, so we just disable
the cache again for the duration of the IROM call.
Also removes a superfluous invalidation line from the bootblock code...
dcache_mmu_enable/disable already take care of that.

This improves firmware boot time substantially. Because cbmem isn't available
yet, we need to allocate some space in sram for the ttb. Doing cache
initialization in the bootblock means we can implement this once per CPU

On x86, cpu_info lives at the top of stack. Make the arm do that as
well, as the threading model needs that and so will multicore support.
As part of this change, make the stack size a power of 2.
Also make it much smaller -- 2048 bytes is PLENTY for ram stage.
Note that the small stack size is counterintuitive for rom stage. How
can this work in rom stage, which needs a HUGE stack for lzma? The
main use of STACK_SIZE has always been in ram stage; since 2002 or so
it was to size per-core stacks (see, e.g.,
src/arch/x86/lib/c_start.S:.space CONFIG_MAX_CPUS*CONFIG_STACK_SIZE
and, more recently, thread stacks. So, we define the STACK_TOP for rom
and ram stage, but the STACK_SIZE has no real effect on the ROM stage
(no hardware red zones on the stack) and hence we're ok with actually
defining the "wrong" stack size. In fact, the coreboot_ram ldscript
for armv7 sizes the stack by subtracting CONFIG_STACK_BOTTOM from
CONFIG_STACK_TOP, so we replicate that arithmetic in bootblock.inc
Observed stack usage in ramstage:
BS: BS_PAYLOAD_LOAD times (us): entry 1 run 153887 exit 1
Jumping to boot code at 23104044
CPU0: stack: 02072800 - 02073000, lowest used address 020728d4, stack used: 1836 bytes
entry = 23104044
Which means we do need 2K, not 1K.

If the size the lzma header claims it needs is bigger than the space we have,
print a message and continue rather than erroring out. Apparently the encoder
is lazy sometimes and just puts a large value there regardless of what the
actual size is.
This was the original intention for this code, but an outdated version of the
patch ended up being submitted.
