In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces
0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.
In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is
assigned for the serial NOR interface.
Going forward, use the latter for the external bus.

Historically (for compatibility with very old platforms), two
different types of micro support cards have been used with the
UniPhier SoC development boards. It has been painful to maintain
both. Having one of them is enough.

These input enable settings are handled by the pinctrl drivers.
Because the external bus pins are input-enabled by default, on-board
devices such as LED still work fine even with this delayed input
enabling.

Add "u-boot,dm-pre-reloc" for device nodes we want in SPL DTB
(spl/u-boot-spl.dtb).
The "soc" node (this is simple-bus node) also needs the property
to bind the pinctrl node located under it.
I am collecting this U-Boot specific hack to the bottom of board
DTS rather than inserting "u-boot,dm-pre-reloc" into SoC DTSI.
My goal is to sync DTSI with Linux for easier maintenance.

Some i.MXes use __NA_ or 0 to avoid setting mux_mode, but the following patch
only take i.MX6/7 into consideration.
"c3c8a5748897b24f18618047804317167a531dd3 imx-common: fix iomux settings"
Use is_soc_type(MXC_CPU_MX7) to avoid breaking other i.MXes when
setting mux_mode.
In this patch, switch to use "asm/imx-common/sys_proto.h" to avoid
build break for "is_soc_type" for vf610 and mx25.

When setting iomux for a pin mux, there is no need to check mux_ctrl_ofs.
Also If still checking mux_ctrl_ofs, we have no chance to set iomux
for i.MX7D IOMUXC_LPSR_SW_MUX_CTL_PAD_GPIO1_IO00, because the mux_ctrl_ofs
for this register is 0.

Quark SoC does not support MSR MTRRs. Fixed and variable range MTRRs
are accessed indirectly via the message port and not the traditional
MSR mechanism. Only UC, WT and WB cache types are supported.
We configure all the fixed range MTRRs with common values (VGA RAM
as UC, others as WB) and 3 variable range MTRRs for ROM/eSRAM/RAM as
WB, which significantly improves the boot time performance.
With this commit, it takes only 2 seconds for U-Boot to boot to shell
on Intel Galileo board. Previously it took about 6 seconds.

Enabling a PLL while IDDQ is high. The Linux kernel checks for this
condition and warns about it verbosely, so while this seems to work
fine, fix it up according to the programming guidelines provided in
the Tegra K1 TRM (v02p), Section 5.3.8.1 ("PLLC and PLLC4 Startup
Sequence"). The Tegra114 TRM doesn't contain this information, but
the programming of PLLC is the same on Tegra114 and Tegra124.

While clk_m and the oscillator run at the same frequencies on Tegra114
and Tegra124, clk_m is the proper source for the architected timer. On
more recent Tegra generations, Tegra210 and later, both the oscillator
and clk_m can run at different frequencies. clk_m will be divided down
from the oscillator.

On currently supported SoCs, clk_m always runs at the same frequency as
the oscillator input. However newer SoC generations such as Tegra210 no
longer have that restriction. Prepare for that by separating clk_m from
the oscillator clock and allow SoC code to override the clk_m rate.

AFAIK, for all PLLs on all Tegra SoCs, the primary PLL output frequency
is (input * m) / (n * p). However, PLLP's primary output (pllP_out0) on
T210 is the VCO output, and divp is not applied. pllP_out2 does have divp
applied. All other pllP_outN are divided down from pllP_out0. We only
support pllP_out0 in U-Boot at the time of writing.
Fix clock_get_rate() to handle this special case.
This corrects the returned rate for PLLP to be 408MHz rather than 204MHz.
In turn, this causes high enough dividers to be calculated for the various
peripheral clocks that feed off of PLLP. Without this, some peripherals
failed to operate correctly. For instance, one of my SD cards worked
perfectly but an older (presumably slower) card could not be read.
Note that prior to commit 722e000ccd72 "Tegra: PLL: use per-SoC pllinfo
table instead of PLL_DIVM/N/P, etc.", the calculated PLL frequency was
816MHz since the wrong values were being extracted from the PLLP divider
register. This caused overly large peripheral dividers to be calculated,
which while wrong, didn't cause any correctness issues; things simply ran
slower than they could.

This arch does not seem to be supported / used at all in the current
U-Boot mainline source tree any more. So lets remove the core u8500 code
and code that was only referenced by this platform.
Please note that this patch also removes these config options:
- CONFIG_PL011_SERIAL_RLCR
- CONFIG_PL011_SERIAL_FLUSH_ON_INIT
As they only seem to be referenced by u8500 based boards. Without any
such board in the current code, these config option don't make sense
any more. Lets remove them as well.
If someone still wants to use this platform, then please send patches
to re-enable support by adding at least one board that references this
code.

This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk,
the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are:
1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC.
2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk
supports 512MB DDR3
3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package.
This patch add the following:
1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size()
2. Introduce a macro is_mx6ul_9x9_evk using
CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL
part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work,
so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with
mx6ul_14x14_evk. And we have no way to dymaically checking this chip
is 9x9 or 14x14.
3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations.
POWER related configurations also effect for mx6ul_14x14_evk. But
power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to
do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk.
4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM
configurations.
5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file
according to board_rev and board_name.
6. Add TARGET_MX6UL_9X9_EVK Kconfig entry
