Furquan Shaikh 4aa761616b arm64: Make exceptions use the transition library
Transition library acts as a common interface for handling exceptions. The only
thing that needs to be implemented by exception.c is the exc_dispatch routine to
handle the exceptions as required.

TEST=Compiles successfully and exceptions are tested using test_exc

Furquan Shaikh 668316bdcc arm64: Add support for transition library
Transition library provides the following functionalities:
1) Setup the environment for switching to any particular EL and jump to the
loaded program at that EL. In short "Execute program X at exception level Y
using the state Z"
2) Provides routines for exception entry and exception exit that can be used by
any program to implement exception handling. The only routine required by the
program would be exc_dispatch which handles the exception in its own required
way and returns by making a call to exc_exit. On exc_exit, the transition
library unwinds the whole stack by popping out the saved state of xregs

Furquan Shaikh c4fb61385f arm64: Reinit free_idx to 1 in mmu_init
If mmu_init is called more than once then, free_idx should be reset to
1. Here, the assumption would be that mmu_init will not be called more than
once. However, this is not necessarily true. Thus, free_idx should be reset to 1
every time we are initializing ttb from scratch.

Ionela Voinescu 00903e5fc0 cbfs/rmodule: add architecture specific operations at stage load
Two weak functions were added so that architecture specific operations
on each segment of payload or stage can be performed.
Each architecture must define its own operations, otherwise the
behavior will default to do-nothing functions.

This patch has been updated by to fit more in line with
how program loading is currently being done. The API is the
same as the original, but all call sites to stages/payloads
have been updated. This is known to break any archs that use
rmodule loading that needs cache maintenance. That will be fixed
in a forthcoming patch. Also, the vboot paths are left as is
for easier upstreaming of the rest of the vboot patches.

Ionela Voinescu 49aad6b387 soc/imgtec/pistachio: Add IMGTEC SPI controller driver
The Serial Peripheral Flash Interface (SPFI) block allows
communication with various devices over the SPI bus.

It uses a configurable transaction interface and it clocks
the bus according to the configured command, address, gap (aka
dummy) and data lengths.

This controller requires the SPI_ATOMIC_SEQUENCING flag set
(write and read done in the same transaction) as it cannot
directly control CS and will assert/de-assert CS at the
beginning/end of a transaction itself.

Note that the size of any transfer cannot be greater than
64KB - 1, as this is configured in a 16-bit field.

The SOC has 2 SPFI interfaces each of them providing 5 slave select
lines. SPFI 0 supports single and dual modes, SPFI 1 supports
single, dual and quad modes.

For SPFI interface 0:
 - The block needs the system PLL and the following top level
   SPI clock registers to be set:
   - CR_cr_top_spi0clkinternal_CTRL[2:0] with division value
   - CR_MIPS_CLOCK_GATE[19]: bit cr_top_SPI0CLKOUT_MIPS set
   - CR_cr_top_SPI0CLKOUT_CTRL[6:0] with division value
 - The following MFIO configuration parameters are also required:
   Signal name		Pad name        MFIO mode
   spim0_d0_txd		MFIO_MIPS_10	0
   spim0_d1_rxd		MFIO_MIPS_9	0
   spim0_mclk		MFIO_MIPS_8	0

   spim0_cs3		MFIO_MIPS_56	1
			MFIO_MIPS_29	1
   spim0_cs4		MFIO_MIPS_57	1
			MFIO_MIMPS_30	1

For SPFI interface 1:
 - The block needs the system PLL and the following top level
   SPI clock registers to be set:
   - CR_cr_top_spi1clkinternal_CTRL[2:0] with division value
   - CR_MIPS_CLOCK_GATE[20]: bit cr_top_SPI1CLKOUT_MIPS set
   - CR_cr_top_SPI1CLKOUT_CTRL[6:0] with division value
 - The following MFIO configuration parameters are also required:
   Signal name		Pad name	MFIO mode

Furquan Shaikh 8fdcf3287c tegra132: Fix clock apis
Instead of directly using the clk_src_id based on enum for clock source, every
device needs to have its own set of clk source ids defined. This prevents
accidentally selecting a wrong clk source if the ids are different from host1x's.
Also, clk_src_id is separated from clk_src_freq_id. clk_src_id is the clk src id
represented in CLK_SOURCE_<dev> registers, whereas clk_src_freq_id is used for
handling the common clock sources based on id to get the proper frequency in
software.

Aaron Durbin b90cd4db40 ryu: remove call to soc_configure_i2c6pad()
This function is breaking display bring up in the kernel. While
this functionality may be needed it's not until there is a
necessity to beep and/or bring up the display in firmware.

BUG=chrome-os-partner:31820
BRANCH=None
TEST=Sean ran with this patch and the display indeed did come up.

The kernel doesn't have the logic for bringing up the plld.
Therefore, configure it in the firmware. The clock used
