When enabling the DCU and pixel clock, the test mode is activated
since this is the reset configuration. The test mode immediately
shows a red screen on a LCD. A moment later, the DCU gets
initialized properly.
This patch enables the pixel clock after initialization of the DCU
control register. This avoids this initial flicker on LCD screens.
While at it change the polarity of pixel clock to display samples
data on the rising edge.

Fix the framebuffer location to the very end of the available memory.
This allows to remove the area from available memory for the kernel,

sdhci_transfer_data() function transfers the blocks passed up to the
number of blocks defined in mmc_data, but returns immediately once all
the blocks are transferred, even if the loop exit condition is not met
(bit SDHCI_INT_DATA_END set in the STATUS word).
When doing multiple writes to mmc, returning right after the last block
is transferred can cause the write to fail when sending the
MMC_CMD_STOP_TRANSMISSION command right after the
MMC_CMD_WRITE_MULTIPLE_BLOCK command, leaving the mmc driver in an
unconsistent state until reboot. This error was observed in the rpi3
board.
This patch waits for the SDHCI_INT_DATA_END bit to be set even after
sending all the blocks.
Test: Reliably wrote 2GiB of data to mmc in a rpi3.

There is a strange interaction with drivers which use DMA if the cache
starts off in a dirty state. Buffer space which the driver reads (but has
not previously written) can contain zero bytes from alloc_priv(). This can
cause corruption of the memory used by DMA for incoming data.
Fix this and add a comment to explain the problem.

Add a specific serial driver for Intel MID platforms.
It has special fractional divider which can be programmed via UART_PS,
UART_MUL, and UART_DIV registers.
The UART clock is calculated as
UART clock = XTAL * UART_MUL / UART_DIV
The baudrate is calculated as
baud rate = UART clock / UART_PS / DLAB
Initialize fractional divider correctly for Intel Edison platform.
For backward compatibility we have to set initial DLAB value to 16
and speed to 115200 baud, where initial frequency is 29491200Hz, and
XTAL frequency is 38.4MHz.

Various commands to NAND flash results in the NAND flash becoming busy.
For those commands the SoC should wait until the NAND indicates it is
no longer busy before sending further commands. However, there is a delay
between the time the SoC sends its last command and when the NAND flash
sets its Ready/Busy Pin. This delay (tWB) must be respected or the SoC may
falsely assume the flash is ready when in reality it just hasn't had enough
time to indicate that it is busy.
Properly delaying by tWB is already done for nand_command/nand_command_lp
in nand_base.c including the version of it in the Linux kernel. Therefore,
this patch brings the handling of tWB delay inline to nand_base.c

The default U-Boot offset for the Allwinner SoCs was set to 32kB.
This was probably to try to maintain some compatibility with the current
image that we build for the MMC where the U-Boot binary is also located at
a 32kB offset.
However, this causes a number of issues. The first one is that it prevents
us from using a backup SPL entirely, which is troublesome in case where the
first would be corrupt (especially on MLC which have a higher number of
bitflips).
We also cannot use the original MMC image on the NAND, because we need to
prepare the SPL image to include the ECCs and randomizer settings, which
reduces the interest of setting it at that particular offset.
It also prevents us from upgrading and flashing the U-Boot and SPLs
independantly, since it's very likely that it will fall in the same erase
block.
Since that default wasn't used by any board, change it for 8MB, which will
be in an erase block of its own, all the erase blocks being multiple of
two. The highest erase block size we encountered is 4MB, which means that
in this particular setup, the first and second erase blocks will be for the
SPL and its backup, and the third for U-Boot.

When trying to autodetect the ECC and randomization configurations, the
driver starts with a randomization disabled and no seeds.
In this case, the number of seeds is obviously 0, and the randomize boolean
is set to false.
However, the logic that retrieves the seed for a given page offset will
blindly use the number of seeds, without testing if the randomization is
enabled, basically doing a modulo by 0.
As it turns out, the libgcc in the common toolchain returns 0 here, which
was our expected value in such a case, and why we would not detect it.
However, U-Boot's libgcc will for some reason return from the function
instead, resulting in an error to load the U-Boot binary in the SPL.
