e8d3eaadcd treewide: Test on CONFIG_USB_HOST (or CONFIG_CMD_USB) not CONFIG_USB
As the logic here is only used when we have a USB host controller, test
on CONFIG_USB_HOST rather than CONFIG_USB in general.  This lets us move
towards using CONFIG_USB only as a menu symbol to say that we have some
form of USB, and then USB_HOST or USB_GADGET depending on the role that
USB plays within the build.

3fa03bcf8c tegra: Test on CONFIG_CMD_USB being enabled for distro bootcmd
Reuse the common logic to allow for BOOT_TARGET_DEVICES to list USB as a
possibility if we're building for a platform that will have USB but not
if we don't, so that we don't hit the link-time check for trying to have
USB boot on a non-USB system.

ddf67daac3 efi_capsule: Move signature from DTB to .rodata
The capsule signature is now part of our DTB.  This is problematic when a
user is allowed to change/fixup that DTB from U-Boots command line since he
can overwrite the signature as well.
So Instead of adding the key on the DTB, embed it in the u-boot binary it
self as part of it's .rodata.  This assumes that the U-Boot binary we load
is authenticated by a previous boot stage loader.

0980164b13 image: Add support for placing crypto_algo in linker lists
The purpose of this change is to enable crypto algorithms to be placed
in linker lists, rather than be declared as a static array. The goal
is to remove the crypto_algos array in a subsequent patch.

Create a new linker list named "cryptos", and search it when
image_get_crypto_algo() is invoked.

NOTE that adding support for manual relocation of crypto_algos within
linker lists is beyond the scope of this patch.

f75b7b82a3 Nokia RX-51: Load bootmenu also from uSD card
By default bootmenu is loaded only from eMMC. After this change U-Boot
first tries to load bootmenu from uSD card and if it fails then fallback to
eMMC. People want to boot alternative OS from removable uSD without need to
modify eMMC content. So this backward compatible change allows it.

Part of this change is also optimization of trymmc* macros so they can be
used in preboot macro for loading bootmenu.

7bafe88620 soc: ti: pruss: Add a platform driver for PRUSS in TI SoCs
The Programmable Real-Time Unit - Industrial Communication
Subsystem (PRU-ICSS) is present of various TI SoCs such as
AM335x or AM437x or the AM654x family. Each SoC can have
one or more PRUSS instances that may or may not be identical.

The PRUSS consists of dual 32-bit RISC cores called the
Programmable Real-Time Units (PRUs), some shared, data and
instruction memories, some internal peripheral modules, and
an interrupt controller. The programmable nature of the PRUs
provide flexibility to implement custom peripheral interfaces,
fast real-time responses, or specialized data handling.

Add support for pruss driver. Currently am654x family
is supported.

a4c577f981 mmc: mmc_get_op_cond: Allow quiet detection of eMMC
Add a new 'quiet' argument to mmc_get_op_cond() function which avoids
printing error message when SD/eMMC card is not detected.

Espressobin and mx6cuboxi boards use this function for detecting presence
of eMMC and therefore it is expected and normal that eMMC does not have to
be connected. So error message "Card did not respond to voltage select!"
should be skipped in this case as it is not an error.

3f6e4ec7c3 power: pmic: Add driver for ST-Ericsson AB8500 via PRCMU
All devices based on ST-Ericsson Ux500 use a PMIC similar to AB8500
(Analog Baseband). There is AB8500, AB8505, AB9540 and AB8540
although in practice only AB8500 and AB8505 are relevant since the
platforms with AB9540 and AB8540 were cancelled and never used in
production.

In general, the AB8500 PMIC uses I2C as control interface, where the
different register banks are represented as separate I2C devices.
However, in practice AB8500 is always connected to a special I2C bus
on the DB8500 SoC that is controlled by the power/reset/clock
management unit (PRCMU) firmware.

Add a simple driver that allows reading/writing registers of the
AB8500 PMIC. The driver directly accesses registers from the PRCMU
parent device (represented by syscon in U-Boot). Abstracting it
further (e.g. with the i2c uclass) would not provide any advantage
because the PRCMU I2C bus is always just connected to AB8500 and
vice-versa.

The ab8500.h header is mostly taken as-is from Linux (with some
minor adjustments) to allow using similar code in both Linux and
U-Boot.

e2f82f93f8 board: stemmy: Copy atags for booting downstream/vendor kernel
The U-Boot "stemmy" board is mainly intended to simplify booting
mainline Linux on various smartphones from Samsung based on ST-Ericsson
Ux500. While the mainline kernel is working great, there are still some
features missing there. In particular, it is currently not possible to
charge the battery when using the mainline kernel.

This means that it is still necessary to boot the downstream/vendor
kernel from Samsung sometimes to charge the device. That kernel is
ancient, still uses board files + ATAGS instead of device trees and
relies on a strange very long kernel command line hardcoded in the
Samsung bootloader.

Actually, since mainline is booted with device trees there is a very
simple way to make the old downstream kernel work as well: We can
simply take most of the ATAGS passed to U-Boot from the Samsung
bootloader and copy them as-is when booting a kernel without device
tree. That way the long command line and other needed ATAGS are copied
as-is without having to bother with them.

The only exception is the ATAG_INITRD - since the initrd is loaded
by U-Boot, the atag for that should be generated in U-Boot so it points
to the correct address. All other ATAGS are copied as-is and not
generated in U-Boot.

Also use the chance and provide a serial# for U-Boot by parsing the
ATAG_SERIAL that is also passed by the Samsung bootloader.

03585d52fc board: stemmy: Parse atags to get available memory
At the moment the "stemmy" board attempts to detect the RAM size with
a simple memory test (get_ram_size()). Unfortunately, this does not work
correctly for devices with 768 MiB RAM (e.g. Samsung Galaxy Ace 2
(GT-I8160), "codina"). Reading/writing memory after the 768 MiB RAM
succeeds but actually overwrites some earlier parts of the memory.

For U-Boot this does not result in any major problems, but on Linux
this will eventually lead to strange crashes because of the memory
corruption.

Since the "stemmy" U-Boot port is designed to be chainloaded from
the original Samsung bootloader, the most reliable way to get the
available amount of RAM is to look at the ATAGS passed by the Samsung
bootloader. Fortunately, the header used to generate ATAGS in U-Boot
(asm/setup.h) can also be easily used to parse them.

Also clarify and simplify stemmy.h a bit to make it more clear where
some of the magic values in there are actually coming from.

98c14ff019 remove struct uclass_driver::ops
Each _device_ belonging to a given uclass of course has its own ->ops,
of a type determined by and known to the uclass.

However, no instance of a uclass_driver seems to populate ->ops, and
the only reference to it in code is this relocation.

Moreover, it's not really clear what could sensibly be assigned; it
would have to be some "struct uclass_ops *" providing a set of methods
for the core to call on that particular uclass, but should the need
for that ever arise, it would be better to have a member of that
particular type instead of void*.

8a44fe6943 board: riscv: add openpiton-riscv64 SoC support
This patch adds openpiton-riscv64 SOC support. In particular, this
board supports a standard bootflow through zsbl->u-boot SPL->
opensbi->u-boot proper->Linux. There are separate defconfigs for
building u-boot SPL and u-boot proper

fe01f41d57 riscv: sifive: Set default fdtfile names
Set default fdtfile names for unleashed and unmatched boards, as used
in the upstream Linux kernel. This allows sysboot command to find and
load appropriate dtb for the matching kernel from universal stock
Ubuntu RISC-V rootfs images based on fdtdir setting in extlinux.conf.
