Our CBFS header offset on rk3288 was very low and overlapped with the
end of the bootblock on recent Pinky builds. This can create all kinds
of fun effects like BSS variables suddenly being initialized to
something else than zero, in an effect that jumps somewhere else for
every slightest code size change.
This patch moves the CBFS header offset up a bit and the CBFS ROM offset
down (because there's really no point in leaving such a large gap). This
resolves our immediate booting problems, and I'll also start on a patch
to add further checks somewhere that catch these overlaps in the future.

This patch runs basic NAND initialization code on Proto 0.2 boards which
have been reworked for NAND. It makes sense to do this in coreboot for
two reasons:
- In general, it is reasonable for coreboot to initialize clocks and such
in preparation for depthcharge's use. Waiting times can be pooled, and
the initialization itself here is very fast.
- There is a kernel bug which requires that the clock is already initialized
before the kernel loads NAND support. coreboot is a more sensible place
to put a workaround than depthcharge because depthcharge initializes
things lazily, but when booting from USB, depthcharge won't need to look
at NAND.
This change involves bringing in an additional header file, ebi2.h, from U-Boot.
TEST=Booted a kernel from USB and verified that NAND came up without any
depthcharge hacks, whereas previously a USB-booted kernel would be unable
to access NAND even with the same drivers compiled in due to an initialization
failure.

The function to read board IDs from tristate GPIOs currently supports
two output modes: a normal base-3 integer, or a custom format where
every two bits represent one tristate pin. Each board decides which
representation to use on its own, which is inconsistent and provides
another possible gotcha to trip over when reading unfamiliar code.
The two-bits-per-pin format creates the additional problem that a
complete list of IDs (such as some boards use to build board-ID tables)
necessarily has "holes" in them (since 0b11 does not correspond to a
possible pin state), which makes them extremely tricky to write, read
and expand. It's also very unintuitive in my opinion, although it was
intended to make it easier to read individual pin states from a hex
representation.
This patch switches all boards over to base-3 and removes the other
format to improve consistency. The tristate reading function will just
print the pin states as they are read to make it easier to debug them,
and we add a new BASE3() macro that can generate ternary numbers from
pin states. Also change the order of all static initializers of board ID
pin lists to write the most significant bit first, hoping that this can
help clear up confusion about the endianness of the pins.

We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).
It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.
For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

We have two drivers for a 100%-identical peripheral right now, mostly
because we couldn't come up with a good common name for it back when we
checked it in. That seems like a pretty silly reason in the long run.
Both Tegra and Rockchip SoCs contain UARTs that use the common 8250
register interface (at least for the very basic byte-per-byte transmit
and receive parts we care about), memory-mapped with a 32-bit register
stride. This patch combines them to a single 8250_mmio32 driver (which
also fixes a problem when booting Rockchip without serial enabled, since
that driver forgot to check for serial initialization when registering
its console drivers). The register accesses are done using readl/writel
(as Rockchip did before), since the registers are documented as 32-bit
length (with top 24 bits RAZ/WI), although the Tegra SoC doesn't enforce
APB accesses to have the full word length. Also fixed checkpatch stuff.
A day may come when we can also merge this driver into the (completely
different, with more complicated features and #ifdefs) 8250 driver for
x86 (which has MMIO support for 8-bit register stride only), both here
and in coreboot. But it is not this day. This day I just want to get rid
of a 99% identical file without expending too much effort.

Don't attempt to scan the PCI bus if the bridge is disabled. When
the PCI bridge is not setup and enabled, it is possible for the
secondary bus register to contain the value zero (0). In this case
the usb_scan_pci_bus routine gets into an infinite recursive loop
which ends only when the heap or stack is exhausted. This patch
verifies that the PCI bridge is enabled by verifying that it is
enabled for either memory or I/O operations. When enabled, the
secondary bus is scanned.

In order to properly support more arm64 SoCs PSCI needs
to handle the hierarchy of cpus/clusters within the SoC.
The nodes within PSCI are kept in a tree as well as
a depth-first ordered array of same tree. Additionally,
the PSCI states are now maintained in a hierachal manner.
OFF propogates up the tree as long as all siblings are
set to OFF. ON propogates up the tree until a node is
not already set to OFF.
The SoC provides the operations for determining how many
children are at a given affinity level. Lastly, the
secmon startup has been reworked in that all non-BSP CPUs
wait for instructions from the BSP.
