Before this patch, CONFIG_SYS_BOOTPARAMS_LEN was the same size as
CONFIG_SYS_MALLOC_LEN. So, if malloc() had previously been called, and
initr_malloc_bootparams() was called, it would fail with an out-of-
memory error. This patch fixes this issue by expanding the malloc pool
to 256KB.

This fixes an issue with the saveenv command causing U-Boot to no
longer work on the QEMU Mips pseudoboard. Because the offset of the
environment was being determined by CONFIG_SYS_MONITOR_LEN, and this
value was less than the actual size of U-Boot, saveenv was overwriting
parts of the U-Boot code. Because CONFIG_SYS_MONITOR_LEN is no longer
used on MIPS, this patch removes it and places the environment at the
end of the pseudoboard's 4MB flash.

The RK3399-Q7 ("Puma") SoM exposes UART0 as the Qseven UART (i.e. the
serial line available via standardised pins on the edge connector and
available on a RS232 connector).

To support boards (such as the RK3399-Q7) that require UART0 as a
debug console, we match CONFIG_DEBUG_UART_BASE and add the appropriate
iomux setup to the rk3399 SPL code.

As we are already touching this code, we also move the board-specific
UART setup (i.e. iomux setup) into board_debug_uart_init(). This will
be called from the debug UART init when CONFIG_DEBUG_UART_BOARD_INIT
is set.

As the RK3399 needs to use its board_debug_uart_init() function, we
have Kconfig enable it by default for RK3399 builds.

With everything set up to define CONFIG_BAUDRATE via defconfig and
with to have the SPL debug UART either on UART0 or UART2, the configs
for the RK3399 EVB are then update (the change for the RK3399-Q7 is
left for later to not cause issues on applying the change).

It's caused by the absence of "{ }" in syscon_rk3399.c
,which will lead to memory overflow like below.According
 to Sysmap file ,we can find the function buck_get_value
of rk808 is just follow the compatible struct,the pointer
"of_match" point to "buck_get_value",but it is not a
struct and don't have member of compatible, In this case,
system crash. So,on the face, it looks like that rk808 is
guilty.but he is really innocent.

The RK3399-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3399.

It provides the following feature set:
 * up to 4GB DDR3
 * on-module SPI-NOR flash
 * on-module eMMC (with 8-bit interace)
 * SD card (on a baseboad) via edge connector
 * Gigabit Ethernet w/ on-module Micrel KSZ9031 GbE PHY
 * HDMI/eDP/MIPI displays
 * 2x MIPI-CSI
 * USB
   - 1x USB 3.0 dual-role (direct connection)
   - 2x USB 3.0 host + 1x USB 2.0 (on-module USB 3.0 hub)
 * on-module STM32 Cortex-M0 companion controller, implementing:
   - low-power RTC functionality (ISL1208 emulation)
   - fan controller (AMC6821 emulation)
   - USB<->CAN bridge controller

Note that we use a multi-payload FIT image for booting and have
Cortex-M0 payload in a separate subimage: we thus rely on the FIT
image loader to put it into the SRAM region that ATF expects it in.

The warm-reset of rk3188 socs keeps the remap setting as it was, so if
it was enabled, the cpu would start from address 0x0 of the sram instead
of address 0x0 of the bootrom, thus making the reset hang.

Therefore make sure the remap is disabled before attempting a warm reset.

Cold reset is not affected by this at all.

Most Rockchip socs have the ability to either map the bootrom or a sram
area to the starting address of the cpu by flipping a bit in the GRF.

Newer socs leave this untouched and mapped to the bootrom but the legacy
loaders on rk3188 and before enabled the remap functionality and the
current smp implementation in the Linux kernel also requires it to be
enabled, to bring up secondary cpus.

So to keep smp working in the kernel, mimic the behaviour of the legacy
bootloaders and enable the remap functionality.

The RK3399 hangs during DMA of the Designware MMC controller, when
performing DMA-based transactions in SPL due to the DDR security settings
left behind by the BootROM (i.e. accesses to the first MB of DRAM are
restricted... however, the DMA is likely to target this first MB, as it
transfers from/to the stack).

System security is not affected, as the final security configuration is
performed by the ATF, which is executed after the SPL stage.

With this fix in place, we can now drop 'fifo-mode' in the DTS for the
RK3399-Q7 (Puma).
