Jim Lin 654cf9c2d8 libpayload: EHCI: Support root-hub TT feature
If EHCI controller has TT (Transaction Translator) support in
root-hub, then we need to keep control over this controller when
USB keyboard (low-speed device) is connected to root-hub port.

Need to add "CONFIG_LP_USB_EHCI_HOSTPC_ROOT_HUB_TT=y" to config file
(e.g. payloads/libpayload/configs/config.nyan_big) to support this
feature.

BUG=chrome-os-partner:32355
TEST=Tested on nyan_big platform.
Press ESC+REFRESH+POWER keys on internal keyboard to power up.
Press Left Arrow or Right Arrow on USB keyboard to switch between
"English" and "Default Locale" in coreboot UI. Or unplug and plug
in device and try again.
Root hub <- low-speed USB keyboard
Root hub <- full-speed hub <- low-speed USB keyboard
Root hub <- high-speed hub <- low-speed USB keyboard

Vadim Bendebury 81678809d5 storm: Add board ID calculation function
storm uses three GPIOs in tertiary mode, such that proto0 returns

Vadim Bendebury d36ef6a51d ipq806x: implement GPIO API
Add implementation of the GPIO API defined in src/include/gpiolib.h.
Also, clean up the GPIO driver, make it use pointers instead of
integers for register address.

This requires a touch in the SPI driver, where the CS GPIO is toggled
and in the board function where it enables USB interface.

BUG=chrome-os-partner:30489

Vadim Bendebury 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.

BUG=chrome-os-partner:30489
TEST=verified that nyan_big still reports proper revision ID.

Furquan Shaikh 698562353b libpayload arm64: Add function to get new range from available memranges
Provide a function to obtain a new memrange with requested properties (type,
size, alignment, max_addr and other restrictions) from the set of available
memranges passed in coreboot table. One user of this function would be getting
memrange for dma, another one would be framebuffer.

Aaron Durbin 9425a545d7 libpayload arm64: fix mmu bugs
1. keep functions and objects used entirely within mmu.c as static.
2. DMA region finding needs to terminate. Therefore, the next address
   to be attempted needs to be less then the current end address.
3. Ensure mmu_ranges passed to mmu_init_ranges_from_sysinfo() has
   0 entries marked as used.

Furquan Shaikh 39292638af libpayload arm64: Initialize and enable MMU
What this change does:
1) Initialize limited page tables as soon as we jump into libpayload. Basically
two ranges are initialized. One is for the BASE_ADDRESS and other is for the
coreboot_tables. With page tables initialized and MMU enabled, we jump into
code to parse coreboot tables.
2) Once coreboot tables are parsed and we have complete picture of the memory,
we perform a complete page table initialzation and enable MMU and then jump to
payload.

Additionally, we also:
1) Initialize DMA memory on our own depending upon the memory map. It ensures
that the DMA buffer is placed in 32-bit memory.
