bd19035c1c tegra132: enable pinmux input for PAD_CFG_GPIO_INPUT()
The original intent was to set the equivalent flags by default
for the PAD_CFG_* macros so as not to make the usage too chatty.
The GPIO_INPUT variant didn't have the PINMUX_INPUT_ENABLE field
set. Therefore, automaticaly set it for PAD_CFG_GPIO_INPUT().

44e5e4ce73 tegra132: use pre-existing reset API
coreboot already has a reset API. Utilize it by selecting
HAVE_HARD_RESET. The tegra132 boards have to provide the
hard_reset() implementation as that involves board-specific
bits. The tegra132 code then provides a cpu_reset() routine
that just promotes that call to a hard_reset().

For the existing tegra132 boards remove the unnecessary files
from the build.

TEST=Ensured hard_reset() does something on Ryu.

efddcfbb52 vboot2: separate verstage from bootblock
With CONFIG_RETURN_FROM_VERSTAGE false, the verstage loads the romstage over
the bootblock, then exits to the romstage. this is necessary for some SOC
(e.g. tegra124) which runs the bootblock on a different architecture.

With CONFIG_RETURN_FROM_VERSTAGE true, the verstage returns to the bootblock.
Then, the bootblock loads the romstage over the verstage and exits to the
romstage. this is probably necessary for some SOC (e.g. rockchip) which does not
have SRAM big enough to fit the verstage and the romstage at the same time.

9c9c336464 Generalize revision number calculation function
Some platforms use tertiary interpretation of GPIO input state to
increase number of distinct values represented by a limited number of
GPIOs. The three states are

- external pull down (interpreted as 0)
- external pull up (1)
- not connected (2)

This has been required by Nvidia devices so far, but Exynos and
Ipq8086 platforms need this too.

This patch moves the function reading the tertiary state into the
library and exposes the necessary GPIO API functions in a new include
file. The functions are still supposed to be provided by platform
specific modules.

The function interpreting the GPIO states has been modified to allow
to interpret the state either as a true tertiary number or as a set
two bit fields.

Since linker garbage collection is not happening when building x86
targets, a new configuration option is being added to include the new
module only when needed.

fbff908a74 coreboot classes: Add dynamic classes to coreboot
Provide functionality to create dynamic classes based on program name and the
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class and compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.

One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

c5cd57c330 nyan: Remove broken setup_display() from romstage
This patch removes a chunk of romstage code from Tegra and all Nyan
boards that was supposed to enable some LCD power rails early, but never
really worked. The dev_find_slot() function can only find PCI devices,
which the CPU cluster is not. Since we're done with Nyan-RO and the
ramstage display code is fine as it is, there is no point in trying to
fix this... but we should remove it from ToT lest someone uses it as a
blueprint to add more dead code to future boards.

44f465d21c tegra132: fix Rx FIFO underruns with slower SPI clock
The SPI controller operates on packets which can be variable
length up to 32-bit packets. It also has the ability to be
put in packed or unpacked mode w.r.t each packet. i.e. does
a single fifo register hold >= 1 packet. The current programming
uses 8-bit packets in unpacked mode which means 4 fifo slots
are used for a 32-bit DMA transfter. As the AHB can only operate
on a minimum of 32-bit bursts the triggers need to be programmed
correctly so that there is room for a full 32-bit DMA transaction.

Previously faster SPI clocks just made things magically work.

The Trust Zone carveout registers are only accessible using

In EL3 the CPU is in secure mode, but when the MMU is enabled
the page tables dictate if accesses to certain regions are
secure or not. However, ramstage is currently being loaded
