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

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.

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:

There are some ARMv8/ARMv4 SoC where the ARMv8 part needs to be

Until we need real SMP on ARMv4, work around that situation
with stub defines.

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.
