95e74a3df7 arm: exynos7420: remove custome low level init function
Remove the custom low-level initialization function and reuse the
default low-level initialization function. But this requires the
ARMV8_MULTIENTRY config option to be enabled for Exynos7420.

On Exynos7420, the boot CPU belongs to the second cluster and so
with ARMV8_MULTIENTRY config option enabled, the 'branch_if_master'
macro fails to detect the CPU as boot CPU. As a temporary workaround
the CPU_RELEASE_ADDR is set to point to '_main'.

boolean option withan empty prompt, followed by a menu:

This is not "nice-looking" at all...

Change the logic to make the boolean option a "menuconfig" rather than a
mere "config", so that all dependent options gets groupped under a menu.
The layout is now:

12262340d5 ARM: OMAP3_LOGIC: Update MTD Partition Table
The previous partition table did not support a separate device tree

location of the device tree (labeled as spl-os) for those who
want to use Falcon Mode or use U-Boot to store the Flattened
Device Tree (FDT) to NAND without appending it to the kernel.

This also grows the kernel to 6MB since 4MB was becomming tight

ade243a211 rpi: passthrough of the firmware provided FDT blob
Raspberry firmware used to pass a FDT blob at a fixed address (0x100),
but this is not true anymore. The address now depends on both the
memory size and the blob size [1].

If one wants to passthrough this FDT blob to the kernel, the most
reliable way is to save its address from the r2/x0 register in the
U-Boot entry point and expose it in a environment variable for
further processing.

This patch just does this:
- save the provided address in the global variable fw_dtb_pointer
- expose it in ${fdt_addr} if it points to a a valid FDT blob

There are many different ways to use it. One can, for example, use
the following script which will extract from the tree the command
line built by the firmware, then hand over the blob to a previously
loaded kernel:

fdt addr ${fdt_addr}
fdt get value bootargs /chosen bootargs
bootz ${kernel_addr_r} - ${fdt_addr}

Alternatively, users relying on sysboot/pxe can simply omit any FDT
statement in their extlinux.conf file, U-Boot will automagically pick
${fdt_addr} and pass it to the kernel.

da29f2991d rsa: Verify RSA padding programatically
Padding verification was done against static SHA/RSA pair arrays which
take up a lot of static memory, are mostly 0xff, and cannot be reused
for additional SHA/RSA pairings. The padding can be easily computed
according to PKCS#1v2.1 as:

  EM = 0x00 || 0x01 || PS || 0x00 || T

where PS is (emLen - tLen - 3) octets of 0xff and T is DER encoding
of the hash.

Store DER prefix in checksum_algo and create rsa_verify_padding
function to handle verification of a message for any SHA/RSA pairing.

4886de7608 arm: dra7xx: Unify Android partition table
Make Android partition table the same as for AM57x EVM.

  1. Make "bootloader" partition start from 0x300 sectors offset, so
     DRA7 is bootable in Android mode (see
     CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR option).
  2. Increase "bootloader" partition size, because size of u-boot.img is
     about 632 KiB (when building DT defconfig, with FIT image enabled).
  3. Specify "reserved" partition explicitly, rather than specifying
     "efs" partition start. Reserved area will be used to store U-Boot
     environment on eMMC. It's convenient to have it exposed explicitly
     so we can read/write U-Boot environment.
  4. Keep all Android partitions locations intact, by reducing
     "reserved" partition size. CONFIG_ENV_SIZE is considered.

a42cfa4f82 arm: am57xx: Define Android partition table
"fastboot oem format" command reuses "gpt write" command, which in turn
requires correct partitions defined in $partitions variable. This patch
adds such definition of Android partitions for DRA7XX EVM board.

By default $partitions variable contains Linux partition table. In order
to prepare Android environment one can run next commands from U-Boot
shell:

    => env set partitions $partitions_android
    => env save

After those operations one can go to fastboot mode and perform
"fastboot oem format" to create Android partition table.

While at it, enable CONFIG_RANDOM_UUID to spare user from providing
UUIDs for each partition manually.

9af5ba878a fastboot: Add CONFIG_FASTBOOT_USB_DEV option
Some boards (like AM57x EVM) has USB OTG controller other than 0. So in
order to use correct controller number in compiled environment we should
define CONFIG_FASTBOOT_USB_DEV option.

For example, when doing "fastboot reboot-bootloader" we want to enter
fastboot mode automatically. But to do so we need to provide controller
number to "fastboot" command. If this procedure is defined in some config
which is common to bunch of boards, and boards have different USB
controller numbers, we can't just hardcode "fastboot 0" in the
environment. We need to use configurable option, which this patch adds.

9b46213b4f lpuart: add a get_lpuart_clk function
It's not always true that LPUART clock is CONFIG_SYS_CLK_FREQ. This
patch provides a weak function get_lpuart_clk(), so that the clock
can be ovreridden on a specific board which uses different clock
for LPUART.
