40a808f173 ARCv2: SLC: Make sure busy bit is set properly on SLC flushing
As reported in STAR 9001165532, an SLC control reg read (for checking
busy state) right after SLC invalidate command may incorrectly return
NOT busy causing software to NOT spin-wait while operation is underway.
(and for some reason this only happens if L1 cache is also disabled - as
required by IOC programming model)

Suggested workaround is to do an additional Control Reg read, which
ensures the 2nd read gets the right status.

Same fix made in Linux kernel:

9963890b8b libfdt: fix build with Python 3
For some reason Python 3 seems to think it does not need to build
the library. Using the --force parameter makes sure that the library
gets built always. This is especially important since we move the
library in the next step of the Makefile, hence forcing a rebuild
every time the higher level Makefile triggers a rebuild is required
to make sure the library is always there.

e391b1e64b Makefile: Fix linking with modern binutils
Since Binutils 1a9ccd70f9a7[1] u-boot will not link targets that set
CONFIG_SYS_TEXT_BASE=0 with the following error:

  LD      u-boot
arm-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try
 linking with -N
arm-linux-gnueabi-ld.bfd: final link failed: Bad value

The issue can be reproduced with the bad binutils and the rock2_defconfig
target.

This issue was also encountered by the powerpc kernel[2], with the fix
being to pass --no-dynamic-linker for linkers newer than 2.26 when this
flag was introduced. The option tells ld that the PIE or shared lib does
not need loaded program headers.

Ubuntu Zesty's Binutils 2.27.51.20161202 hits this error.

ca0d29e4f0 x86: Introduce minimal PMU driver for Intel MID platforms
This simple PMU driver allows to tyrn power on and off for selected
devices. In particularly Intel Tangier needs to power on SDHCI
controllers in order to access to them during board initialization.

In the future it might be expanded to cover other Intel MID platforms,
that's why it's located under arch/x86/lib and called pmu.c.

c5f8dd482b serial: Add serial driver for Intel MID
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.

This commit implements the board_fit_image_post_process() function for
the keystone architecture. This function calls into the secure boot
monitor for secure authentication/decryption of the image. All needed
work is handled by the boot monitor and, depending on the keystone
platform, the security functions may be offloaded to other secure
processing elements in the SoC.

The boot monitor acts as the gateway to these secure functions and the
boot monitor for secure devices is available as part of the SECDEV
package for KS2. For more details refer doc/README.ti-secure

6e1eb089be mtd: nand: am335x_spl_bch: Incorporate tWB delay in nand_command function
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

b8c908762c ti: clocks: Fix do_enable_clocks() to accept NULL pointers as input parameters
Up till this commit passing NULL as input parameter was allowed, but not
handled properly.

When one passed NULL to one of this function parameters, the code was
executed causing data abort.

However, what is more interesting, the abort was not caught because of code
execution in HYP mode with masked CPSR A bit ("Imprecise Data Abort mask bit).
The TI's AM57xx SoC switch to HYP mode with A bit masked in lowlevel_init.S
due to SMC call. Such operation (by default) is performed in SoC ROM code.

The problem would pop up when one:
- Switch back to SVC mode after disabling LPAE support
- Somebody enables A bit (by executing cpsie a asm instruction)

and then the previously described exception would be caught.

b09ece0836 common/xyzModem.c: Do not use hard-coded address for debug buffer
Under the plethora of #ifdefs, the xyzModem code hid this pearl:
static char *zm_out = (char *) 0x00380000;
This was only enabled when DEBUG is defined, so it's probably why it
went unnoticed for so long. No idea what platform had memory at that
exact location, but the this approach is extremely hacky.
Use a static buffer instead.
