arm64: Allow exceptions to return
Our current arm64 exception handlers all panic and never return to the
exception triggering code.
But if any handler wanted to continue execution after fixups, it would
need help from the exception handling code to restore all registers.
This patch implements that help. With this code, exception handlers on
aarch64 can successfully return to the place the exception happened (or
somewhere else if they modify elr).

efi_loader: Implement memory allocation and map
The EFI loader needs to maintain views of memory - general system memory
windows as well as used locations inside those and potential runtime service
MMIO windows.
To manage all of these, add a few helpers that maintain an internal
representation of the map the similar to how the EFI API later on reports
it to the application.
For allocations, the scheme is very simple. We basically allow allocations
to replace chunks of previously done maps, so that a new LOADER_DATA
allocation for example can remove a piece of the RAM map. When no specific
address is given, we just take the highest possible address in the lowest
RAM map that fits the allocation size.

efi_loader: Add "bootefi" command
In order to execute an EFI application, we need to bridge the gap between
U-Boot's notion of executing images and EFI's notion of doing the same.
The best path forward IMHO here is to stick completely to the way U-Boot
deals with payloads. You manually load them using whatever method to RAM
and then have a simple boot command to execute them. So in our case, you
would do
# load mmc 0:1 $loadaddr grub.efi
# bootefi $loadaddr
which then gets you into a grub shell. Fdt information known to U-boot
via the fdt addr command is also passed to the EFI payload.

ARM: omap-common: Add standard access for board description EEPROM
Several TI EVMs have EEPROM that can contain board description information
such as revision, DDR definition, serial number, etc. In just about all
cases, these EEPROM are on the I2C bus and provides us the opportunity
to centralize the generic operations involved.
The on-board EEPROM on the BeagleBone Black, BeagleBone, AM335x EVM,
AM43x GP EVM, AM57xx-evm, BeagleBoard-X15 share the same format.
However, DRA-7* EVMs, OMAP4SDP use a modified format.
We hence introduce logic which is generic between these platforms
without enforcing any specific format. This allows the boards to use the
relevant format for operations that they might choose.
This module will compile for all TI SoC based boards when
CONFIG_TI_I2C_BOARD_DETECT is enabled to have optimal build times for
platforms that require this support.
It is important to note that this logic is fundamental to the board
configuration process such as DDR configuration which is needed in
SPL, hence cannot be part of the standard u-boot driver model (which
is available later in the process). Hence, to aid efficiency, the
eeprom contents are copied over to SRAM scratchpad memory area at the
first invocation to retrieve data.
To prevent churn with cases such as DRA7, where eeprom format maybe
incompatible, we introduce a generic common format in eeprom which
is made available over accessor functions for usage.
Special handling for BBG1 EEPROM had to be introduced thanks to the
weird eeprom rev contents used.
The follow on patches introduce the use of this library for AM335x,
AM437x, and AM57xx.

Early clock initialization is currently done in two stages for OMAP4/5
SoCs. The first stage is the initialization of console clocks and
then we initialize basic clocks for functionality necessary for SoC

By splitting up prcm_init and centralizing this clock initialization,
we setup the code for follow on patches that can do board specific
initialization such as board detection which will depend on these
basic clocks.
As part of this change, since the early clock initialization
is centralized, we no longer need to expose the console clock
initialization.
NOTE: we change the sequence slightly by initializing console clocks
timer after the io settings are complete, but this is not expected
to have any functioanlity impact since we setup the basic IO drive
strength initialization as part of do_io_settings.
