98cff66027 sandbox: Introduce Kconfig option for 32/64 bit host
It seems most of the time we are building and running sandbox on 64-bit host.
But we do support 32-bit host as well. Introduce Kconfig option for this.

The IPSR18 register bits were missing from the R8A7795 ES2.0+ PFC

3fe6e6e2aa x86: baytrail: acpi: Add full reset bit to the reset register value in FADT
It was noticed a few times, that the reboot from Linux (reboot command)
is different from the reboot (reset command) under U-Boot. The U-Boot
version does seem to reset the board more deeply (PCI cards etc) than
the Linux reboot.

This is actually caused by missing full reset bit in the reset register
value in the ACPI FADT table.

The SuperH architecture allows to be run in either little or big
endian mode. Some SuperH SoCs get the little vs. big endian decision
through mode pins sampled at reset, so if big endian has been choosen
by HW designers, it cannot be easily changed.

Therefore, it makes sense to allow building U-Boot for SuperH in big
endian mode. To allow this, the only change needed is to adjust the
OUTPUT_FORMAT() in the linker script.

added macros for boot modes, in the process the reserved boot mode got

Some Intel FSP (like Braswell) does SPI lock-down during the call
to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done,
it's bootloader's responsibility to configure the SPI controller's
opcode registers properly otherwise SPI controller driver doesn't
know how to communicate with the SPI flash device.

This introduces a Kconfig option CONFIG_FSP_LOCKDOWN_SPI for such
FSPs. When it is on, U-Boot will configure the SPI opcode registers
before the lock-down.

a3f0a7d5b5 mmc: sh_sdhi: Fix the ACMD handling
The command handling in this driver is awful, esp. because the driver
depends on command numbers to determine whether this is APPCMD or not.
Also, handling of command RSP response types is totally wrong.

This patch at least plucks out some of the custom command encoding and
fixes the APPCMD handling. The RSP handling still needs work, yet that
might not be needed as it turns out the uniphier-sd.c driver is in much
better shape and supports the same IP, so we might be able to just drop
this driver in favor of the uniphier one.

Until these limitations are removed we cannot really support more than one

can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since

0459bc30b6 ARM: OMAP5: Enable support for AVS0 for OMAP5 production devices
OMAP5432 did go into production with AVS class0 registers which were
mutually exclusive from AVS Class 1.5 registers.

Most OMAP5-uEVM boards use the pre-production Class1.5 which has
production efuse registers set to 0. However on production devices,
these are set to valid data.

scale_vcore logic is already smart enough to detect this and use the
"Nominal voltage" on devices that do not have efuse registers populated.

On a test production device populated as follows:
MPU OPP_NOM:
=> md.l 0x04A0021C4 1
4a0021c4: 03a003e9                               ....
(0x3e9 = 1.01v) vs nom voltage of 1.06v
MPU OPP_HIGH:
=> md.l 0x04A0021C8 1
4a0021c8: 03400485                               ..@.

MM OPP_NOM:
=> md.l 0x04A0021A4 1
4a0021a4: 038003d4                               ....
(0x3d4 = 980mV) vs nom voltage of 1.025v
MM OPP_OD:
=> md.l 0x04A0021A8 1
4a0021a8: 03600403                               ..`.

CORE OPP_NOM:
=> md.l 0x04A0021D8 1
4a0021d8: 000003cf                               ....
(0x3cf = 975mV) vs nom voltage of 1.040v

Since the efuse values are'nt currently used, we do not regress on
existing pre-production samples (they continue to use nominal voltage).

But on boards that do have production samples populated, we can leverage
the optimal voltages necessary for proper operation.

Tested on:
a) 720-2644-001 OMAP5UEVM with production sample.
b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.

Data based on OMAP5432 Technical reference Manual SWPU282AF (May
2012-Revised Aug 2016)

3159a6fc39 rockchip: rk3368: remove setup of secure timer from TPL/SPL
When using DM timers w/ the timer0 block within the RK3368, we no
longer depend on the ARMv8 generic timer counting.  This allows us to
drop the secure timer initialisation from the TPL and SPL stages.

The secure timer will later be set up by ATF, which starts the ARMv8
generic timer.  Thus, there will be a dependency from Linux to the ATF
through the ARMv8 generic timer... this seems reasonable, as Linux
will require the ATF (and PSCI) to start up the secondary cores anyway
(in other words: we don't add any new dependencies).

403e9cbcd5 rockchip: rk3368: add DRAM controller driver with DRAM initialisation
This adds a DRAM controller driver for the RK3368 and places it in
drivers/ram/rockchip (where the other DM-enabled DRAM controller
drivers for rockchip devices should also be moved eventually).

At this stage, only the following feature-set is supported:
 - DDR3
 - 32-bit configuration (i.e. fully populated)
 - dual-rank (i.e. no auto-detection of ranks)
 - DDR3-1600K speed-bin

This driver expects to run from a TPL stage that will later return to
the RK3368 BROM.  It communicates with later stages through the
os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR
init code).

Unlike other DMC drivers for RK32xx and RK33xx parts, the required
timings are calculated within the driver based on a target frequency
and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this
time).

The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0)
register for controlling the operation of its (single-channel) DRAM
controller in the GRF block.  This provides for selecting DDR3, mobile
DDR modes, and control low-power operation.
As part of this change, DDRC0_CON0 is also added to the GRF structure
definition (at offset 0x600).

f5a432959a rockchip: clk: rk3368: implement MMC/SD clock reparenting
The original clock support for MMC/SD cards on the RK3368 suffered
from a tendency to select a divider less-or-equal to the the one
giving the requested clock-rate: this can lead to higher-than-expected
(or rather: higher than supported) clock rates for the MMC/SD
communiction.

This change rewrites the MMC/SD clock generation to:
 * always generate a clock less-than-or-equal to the requested clock
 * support reparenting among the CPLL, GPLL and OSC24M parents to
   generate the highest clock that does not exceed the requested rate

In addition to this, the Linux DTS uses HCLK_MMC/HCLK_SDMMC instead of
SCLK_MMC/SCLK_SDMMC: to match this (and to ensure that clock setup
always works), we adjust the driver appropriately.

e6a0586277 armv8: move low-level assembly functions into function-sections
TPL builds today don't need to call into firmware or set up the MMU
(if this changes, it should be controlled through a config option
whether to include this or not), but include the needed support code
for this anyway.  By moving these unused low-level functions into
seperate function-sections, the linker can garbage-collect the unused
sections.

Note that (if DM support is enabled), there will be a call to the
cache-flushing code from alloc_priv(...) in drivers/core/device.c.
This then add 52 bytes of binary size (an increase from 20589 to 20641
bytes) compared to completely removing this code.

Even for a feature-rich TPL (including DM support as for the RK3368),
this equates to a size difference of significantly more than 10% in
TPL binary size.

19b68fb280 rockchip: back-to-bootrom: simplify the #ifdef-check for LIBCOMMON in TPL/SPL
With the finer-grained control over LIBCOMMON_SUPPORT for TPL/SPL (i.e.
with the newly introduced distinction between TPL_LIBCOMMON_SUPPORT and
SPL_LIBCOMMON_SUPPORT), we can simplify the #ifdef-check to simply use
CONFIG_IS_ENABELD.

ee14d29db0 rockchip: back-to-bootrom: split BACK_TO_BOOTROM for TPL/SPL
The back-to-bootrom option is rather unfortunately named
  CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM
instead of
  CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM

To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM),
we need to rename it.  At the same time, we introduce a TPL_ variant of
the option to give us finer-grained control over when it should be used.

This change is motivated by our RK3368 boot process, which returns to
the boot ROM only from the TPL stage, but not from the SPL stage.

36979c7e56 rockchip: back-to-bootrom: add 'back-to-bootrom' support for AArch64
The back-to-bootrom support for Rockchip is equivalent to an
(assembly) implementation of setjmp/longjmp (i.e. it saves the
stack-pointer, link-register and callee-saved registers). Up until
now, this had only been implemented for AArch32 (i.e. ARMv7 or older),
which puts the new ARMv8 devices (which boot in AArch64 mode) at a
slight disadvantage.

To allow use of the 'back-to-bootrom' feature on new devices (e.g. the
RK3368), this commit adds an implementation for AArch64.

225d30b708 spl: add a 'return to bootrom' boot method
Some devices (e.g. the RK3368) have only limited SRAM, but provide
support for loading the next boot stage after our SPL performs basic
setup (e.g. DRAM).

For target systems like these, we add a boot device BOOTROM that will
invoke a board-specific hook to return to the bootrom (if supported).

The problem was indicated by cppcheck.

I do not have the hardware to test if the code change below
leads to a correct system behavior.
