For NXP LPC32xx boards the change enables SPL_DM option, this allows
to use any driver model UART driver in SPL images, hence a restriction
on HSUART in SPL image is removed and well as definitions for non-DM
NS16550 driver, its DM version is used instead.
Because SPL_DM requires malloc(), enable CONFIG_SPL_SYS_MALLOC_SIMPLE
for LPC32xx boards.
The change adds about 5KB to the resulting SPL image (for devkit3250
board SPL image is increased from 10672 to 15608 bytes).

Due to specific of DM NS16550 device description UART clock can not be
got in runtime and by default it is set to 13MHz, if board PERIPH_CLK
is different, this should be specified in board configuration file.
For SPL builds HSUARTs are disabled and non-DM NS16550 driver is

For some board designs, it might be useful to switch the DC-DC

for EMI reasons.
For this, override the mxs_power_setup_dcdc_clocksource function

Example:
void mxs_power_setup_dcdc_clocksource(void)
{
mxs_power_switch_dcdc_clocksource(POWER_MISC_FREQSEL_20MHZ);

DDR has been set as secure in MMU tables. Non-secure master such
as SDHC DMA cannot access data correctly. Mixing secure and non-
secure MMU entries requirs the MMU tables themselves in secure
memory. This patch moves MMU tables into a secure DDR area.
Early MMU tables are changed to set DDR as non-secure. A new
table is added into final MMU tables so secure memory can have
2MB granuality.
gd->secure_ram tracks the location of this secure memory. For
ARMv8 SoCs, the RAM base is not zero and RAM is divided into several
banks. gd->secure_ram needs to be maintained before using. This
maintenance is board-specific, depending on the SoC and memory
bank of the secure memory falls into.

This patch addresses a problem mentioned recently on this mailing list:
[1].
In that posting a LS1021 based system was locking up at about 5 minutes
after boot, but the problem was mysteriously related to the toolchain
used for building u-boot. Debugging the problem reveals a stuck
interrupt 29 on the GIC.
It appears Freescale's LS1021 support in u-boot erroneously sets the
64-bit ARM generic PL1 physical time CompareValue register to all-ones
with a 32-bit value. This causes the timer compare to fire 344 seconds
after u-boot configures it. Depending on how fast u-boot gets the
kernel booted, this amounts to about 5-minutes of Linux uptime before
locking up.
Apparently the bug is masked by some toolchains. Perhaps this is
explained by default compiler options, word sizes, or binutils versions.
At any rate this patch makes the manipulation explicitly 64-bit which
alleviates the issue.

The 3.4 kernel from the Allwinner SDK is clocking AHB1 at 200MHz
on Allwinner H3 and using PLL6 as the clock source (PLL6/3).
This can be verified by reading the value of the AHB1_APB1_CFG_REG
register via /dev/mem. It always reads as 0x3180 regardless of
the current cpufreq operating point. So this configuration should
be safe for use in U-Boot too.
PLL6 also needs to be configured before it is used as the clock
source, according to the "CCU / Programming Guidelines" section
of the Allwinner manual.
The current low AHB1 clock speed is limiting the USB transfer
speed when booting via FEL. This patch can increase the FEL USB
transfer speed from ~510 KB/s to ~950 KB/s.
