e555d4caac pmic: Convert pm8916 driver to a generic Qcom PMIC driver
Since both pm8916.c and pm8916_gpio.c are already supporting multiple
Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and
qcom_pmic_gpio.c respectively. Also, these driver can be extended to
support additional functionality if required for other Qcom SoCs.

Along with this import latest DT binding: qcom,spmi-pmic.txt from Linux
kernel and thereby remove pm8916.txt.

0c1eab6f75 dts: qcs404-evb: Add USB controller and PHY nodes
QCS404 SoC provides support for two USB controllers: one USB3 and the
other one being USB2. The USB3 controller supports further 2 PHY: one high
speed PHY and the other super speed PHY. The USB2 controller supports a
single high speed PHY. So add corresponding DT nodes.

7e3084eda4 board: lsxl: convert to DM_SERIAL
DM_SERIAL needs early malloc. The on-chip RAM is pretty tight, it's only
2kiB, with DM_SERIAL enabled, this doesn't work anymore. Fortunately for
us, we don't need the on-chip RAM because the DRAM is already
initialized before u-boot starts. Just put the early malloc area there
and use the default early malloc size.

7c9bd92eea board: lsxl: convert to DM_GPIO
Use the new mvebu GPIO driver and convert all the function calls to the

uclass and the regulator uclass. Unfortunately, the GPIO LED doesn't
offer a blinking method. Thus we are now stuck with solid on and off
states, which makes debugging a bit harder. Also, there is no GPIO fan

f395cf9cac arm: kirkwood: 88f6281: Detect CONFIG_SYS_TCLK from SAR register
Bit 21 in SAR register specifies if TCLK is running at 166 MHz or 200 MHz.
This information is undocumented in public Marvell Kirkwood Functional
Specifications [2], but is available in Linux v3.15 kirkwood code [1].

Commit 8ac303d49f ("arm: kirkwood: Do not overwrite CONFIG_SYS_TCLK")
broke support for Marvell 88F6281 SoCs because it was expected that all
those SoCs have TCLK running at 200 MHz as specified in Marvell 88F6281
Hardware Specifications [3].

Fix broken support for 88F6281 by detecting CONFIG_SYS_TCLK from SAR
register, like it was doing Linux v3.15.

616278bd2c time: move the CONFIG_SYS_TIMER_RATE handling to the compiler
CONFIG_SYS_TIMER_RATE might be a dynamic value, i.e. a function call
instead of a static value, thus it has to be evaluated at runtime. If it
is a static value, the compiler should be able to optimize the unused
branches out.

This will be needed for kirkwoods dynamic CONFIG_SYS_TCLK setting.

5692e5b244 arm: mvebu: mbus: Fix mbus driver to work also after U-Boot relocation
mbus driver is initialized from arch_cpu_init() callback which is called
before relocation. This driver stores lot of functions and structure
pointers into global variables, so it is data position dependent.

Therefore after relocations all pointers are invalid and driver does not
work anymore as all pointers referes to the old memory, which overlaps with
CONFIG_SYS_LOAD_ADDR and ${loadaddr}.

For example U-Boot fuse command crashes if loadaddr memory is cleared or
rewritten by some image loaded by U-Boot load command.

  mw.w ${loadaddr} 0x0 10000
  fuse read 0 1 2

Fix this issue by removing of all mbus global variables in which are stored
pointers to structures or functions which changes during relocation. And
replace it by direct function calls (not via pointers). With this change
fuse command finally works.

080b7d89ae mtd: rawnand: fsl_elbc: Remove NAND_NO_SUBPAGE_WRITE flag
Subpage write support for freescale eLBC NAND controller driver is
implemented in U-Boot and was fixes in the commit d3963721d9 ("nand: Sync
with Linux v4.1").

So remove NAND_NO_SUBPAGE_WRITE flag from the fsl_elbc_nand.c driver. This
partially revert commit cb04c77234 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE
to eLBC and IFC drivers"), only eLBC driver part.

With this change U-Boot with default settings can read from NAND UBIFS
image created on Linux with Linux default settings. Prior this change
U-Boot was unable to read from NAND UBIFS images created with Linux default
settings due to differnet UBI geometry.

Linux kernel fsl_elbc_nand.c driver also does not set NAND_NO_SUBPAGE_WRITE
flag and has implemented subpage write support.

The board can mount different nand brand type. Try to use the full scan
detection and not the onfi one

007f1d1473 mtd: nand: samsung: Retrieve ECC requirements from extended
Upstream linux commit 8fc82d456e40a0.

On some nand controllers with hw-ecc the controller code wants to know
the ecc strength and size and having these as 0, 0 is not accepted.

Specifying these in devicetree is possible but undesirable as the nand
may be different in different production runs of the same board, so it
is better to get this info from the nand id where possible.

This commit adds code to read the ecc strength and size from the nand
for Samsung extended-id nands. This code is based on the info for the 5th
id byte in the datasheets for the following Samsung nands: K9GAG08U0E,
K9GAG08U0F, K9GAG08X0D, K9GBG08U0A, K9GBG08U0B. These all use these bits
in the exact same way.
