console is Kconfig option a separate defconfig has to be created for each

In order to enable cpsw on AM335x ICEv2 board, the following needs to be done:
1)There are few on board jumper settings which gives a choice between
cpsw and PRUSS, that needs to be properly selected[1]. Even after selecting
this, there are few GPIOs which control these muxes that needs to be held high.
2) The clock to PHY is provided by a PLL-based clock synthesizer[2] connected
via I2C. This needs to properly programmed and locked for PHY operation.
And PHY needs to be reset before before being used, which is also held by
a GPIO.
3) RMII mode needs to be selected.

Adds code to detect AM43xx HS EVMS - the string in the
I2C EEPROM for HS EVMs differs from GP EVMs. Adds code to
for evm detection, regardless of whether the evm is for
GP or HS parts, and updates board init to use that.
Modifies findfdt command to pick up am437x-gp-evm.dtb for

Updates configs/am43xx_evm.h to use CONFIG options from
SOC specific Kconfig file for various calculations.
On AM43x devices, the address of SPL entry point depends on
the device type, i.e. whether it is secure or non-secure.
Further, for non-secure devices, the SPL entry point is different
between USB HOST boot mode, other "memory" boot modes (MMC, NAND)
and "peripheral" boot modes (UART, USB)
To add to the complexity, on secure devices, in addition to the
above differences, the SPL entry point can change because of the
space occupied by other components (other than u-boot or spl)
that go into a secure boot image.
To prevent the user from having to modify source files every time
any component of the secure image changes, the value of
CONFIG_SPL_TEXT_BASE has been set using a Kconfig option that
is supplied in the am43xx_*_defconfig files
Using the CONFIG options also enables us to do away with some
compile time flags that were used to specify CONFIG_SPL_TEXT_BASE
for different boot modes.
On QSPI devices, the same problem described above occurs w.r.t. the
address of the u-boot entry point in flash, when booting secure
devices. To handle this, CONFIG_SYS_TEXT_BASE is also setup via
a Kconfig option and the defconfig files.

Adding support for AM43xx secure devices require the addition
of some SOC specific config options like the amount of memory
used by public ROM and the address of the entry point of u-boot
or SPL, as seen by the ROM code, for the image to be built
correctly.
This mandates the addition of am AM43xx CONFIG option and the
ARM Kconfig file has been modified to source this SOC Kconfig
file. Moving the TARGET_AM43XX_EVM config option to the SOC
KConfig and out of the arch/arm/Kconfig.
Updating defconfigs to add the CONFIG_AM43XX=y statement and
removing the #define CONFIG_AM43XX from the header file.

Some hardware that is supported by U-Boot can not handle DMA above 32bits.
For these systems, we need to come up with a way to expose the disk interface
in a safe way.
This patch implements EFI specific bounce buffers. For non-EFI cases, this
apparently was no issue so far, since we can just define our environment
variables conveniently.

Now that we can expose network functionality to EFI applications,
the logical next step is to load them via pxe to execute them as
well.
This patch adds the necessary bits to the distro script to automatically
load and execute EFI payloads. It identifies the dhcp client as a uEFI
capable PXE client, hoping the server returns a tftp path to a workable
EFI binary that we can then execute.
To enable boards that don't come with a working device tree preloaded,
this patch also adds support to load a device tree from the /dtb directory
on the remote tftp server.

A mailbox is a hardware mechanism for transferring small message and/or
notifications between the CPU on which U-Boot runs and some other device
such as an auxilliary CPU running firmware or a hardware module.
This patch defines a standard API that connects mailbox clients to mailbox
providers (drivers). Initially, DT is the only supported method for
connecting the two.
The DT binding specification (mailbox.txt) was taken from Linux kernel
v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.

The current reset API implements a method to reset the entire system.
In the near future, I'd like to introduce code that implements the device
tree reset bindings; i.e. the equivalent of the Linux kernel's reset API.
This controls resets to individual HW blocks or external chips with reset
signals. It doesn't make sense to merge the two APIs into one since they
have different semantic purposes. Resolve the naming conflict by renaming
the existing reset API to sysreset instead, so the new reset API can be
called just reset.

The exynos5 platforms use DM in U-Boot and do not use DM in SPL. The serial
driver, serial_s5p.c, is DM-only. This is OK for U-Boot, but in SPL, this
will fail with the following compile error:
drivers/built-in.o: In function `get_current':
...u-boot/drivers/serial/serial.c:387: undefined reference to `default_serial_console'
This warning happens because common/console.c is compiled into U-Boot SPL
if CONFIG_SPL_SERIAL_SUPPORT . The common/console.c invokes serial_*()
functions and since exynos5 does not use DM in SPL, these functions come
from drivers/serial/serial.c . The serial_*() locate default serial port
by calling default_serial_console(), but because the serial_s5p.c is DM-only,
it does no longer define default_serial_console(). Thus the error.

The address of the UART differs based upon the system controller because
it's actually within the I/O port region, which is in a different
location for each system controller. Rather than handling this as 2
UARTs with the correct one selected at runtime, use I/O port accessors
for the UART such that access to it gets translated into the I/O port
region automatically.

The current SPL header, created by the 'mksunxiboot' tool, has size
32 bytes. But the code in the boot ROM stores the information about
the boot media at the offset 0x28 before passing control to the SPL.
For example, when booting from the SD card, the magic number written
by the boot ROM is 0. And when booting from the SPI flash, the magic
number is 3. NAND and eMMC probably have their own special magic
numbers too.
Currently the corrupted byte is a part of one of the instructions in
the reset vectors table:
b reset
ldr pc, _undefined_instruction
ldr pc, _software_interrupt <- Corruption happens here
ldr pc, _prefetch_abort
ldr pc, _data_abort
ldr pc, _not_used
ldr pc, _irq
ldr pc, _fiq
In practice this does not cause any visible problems, but it's still
better to fix it. As a bonus, the reported boot media type can be
later used in the 'spl_boot_device' function, but this is out of
the scope of this patch.
