b9297c2266 ARM: cache_v7: Various minor cleanups
Remove two gratuituous blank lines, uses u32 (instead of int) as the
type for values that will be written to a register, moves the beginning
of the variable declaration section to a separate line (rather than the
one with the opening brace) and keeps the function signature on a single
line where possible.

b67932e3e7 ARM: UniPhier: call pin_init() also in the normal boot
CONFIG_UNIPHIER_SERIAL has been moved to Kconfig and
it is defined in ./.config but not in spl/.config,
so pin_init() should be called from the normal image
so that UART works correctly.

b603c68129 ARM: UniPhier: reset on-board devices on start-up
If a support card is attached to the main board, the on-board
SMSC9118 LAN controller is available.  It must be kept in reset
state for a while on start-up.

When the board is kicked via a debbuger rather than pushing the
hardware reset button, on-board chips are not reset; in this case
the reset signals should be asserted by software.

This module controls clocks and resets for RTC block modules, and also
PLL biasing in the main clock module.

This patch adds the register definitions, and also enables the clocks

d064cbffff dm: serial: use Driver Model for UniPhier serial driver
This commit converts UniPhier on-chip serial driver to driver model.

Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)

Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.

Tested on UniPhier PH1-LD4 ref board.

89f44bb0ce keystone2: ecc: add ddr3 error detection and correction support
This patch adds the DDR3 ECC support to enable ECC in the DDR3
EMIF controller for Keystone II devices.

By default, ECC will only be enabled if RMW is supported in the
DDR EMIF controller. The entire DDR memory will be scrubbed to
zero using an EDMA channel after ECC is enabled and before
u-boot is re-located to DDR memory.

An ecc_test environment variable is added for ECC testing.
If ecc_test is set to 0, a detection of 2-bit error will reset
the device, if ecc_test is set to 1, 2-bit error detection
will not reset the device, user can still boot the kernel to
check the ECC error handling in kernel.

The (removed) mx35 timer code (specifically __udelay()) could deadlock at

cast up to a 64-bit value.  If get_ticks() + tmo in __udelay() crossed

locks the processor.  Rather than patch the specific mx35 issues, simply

08155289a4 arm: mx6: ddr: configure MMDC for slow_pd
According to MX6 TRM, both MMDC and DRAM should be configured to
the same powerdown precharge. Currently, mx6_dram_cfg()
configures MMDC for fast pd (MDPDC[7] = 0), and the DRAM for
'slow exit (DLL off)' (MR0[12] = 0).

Configure MMDC for slow pd.

aeb3fcb359 ARM: tegra: Use mem size from MC rather than ODMDATA
In at least Tegra124, the Tegra memory controller (MC) has a register
that controls the memory size. Read this to determine the memory size
rather than requiring this to be redundantly encoded into the ODMDATA.
This way, changes to the BCT (i.e. MC configuration) automatically
updated SW's view of the memory size, without requiring manual changes
to the ODMDATA.

Future work potentially required:
* Clip the memory size to architectural limits; U-Boot probably doesn't
  and won't support either LPAE or Tegra's "swiss cheese" memory layout,
  at least one of which would be required for >2GB RAM.
* Subtract out any carveout required by firmware on future SoCs.

Because all the major bugs in the DRAM initialization sequence are
now hopefully fixed, it should be safe to re-initialize the DRAM
controller multiple times until we get it configured right. The
original Allwinner's boot0 bootloader also used a similar
autodetection trick.

The DDR3 spec contains the package pinout and addressing table for
different possible chip densities. It appears to be impossible to
distinguish between a single chip with 16 I/O data lines and a pair
of chips with 8 I/O data lines in the case if they provide the same
storage capacity. Because a single 16-bit chip has a higher density
than a pair of equivalent 8-bit chips, it has stricter refresh timings.
So in the case of doubt, we assume that 16-bit chips are used.
Additionally, only Allwinner A20 has all A0-A15 address lines and
can support densities up to 8192. The older Allwinner A10 and
Allwinner A13 can only support densities up to 4096.

We deliberately leave out DDR2, dual-rank configurations and the
special case of a 8-bit chip with density 8192. None of these
configurations seem to have been ever used in real devices. And no
new devices are likely to use these exotic configurations (because
only up to 2GB of RAM can be populated in any case).

This DRAM autodetection feature potentially allows to have a single
low performance fail-safe DDR3 initialiazation for a universal single
bootloader binary, which can be compatible with all Allwinner
A10/A13/A20 based devices (if the ifdefs are replaced with a runtime
SoC type detection).

935758b1d5 sunxi: dram: Derive write recovery delay from DRAM clock speed
The write recovery time is 15ns for all JEDEC DDR3 speed bins. And
instead of hardcoding it to 10 cycles, it is possible to set tighter
timings based on accurate calculations. For example, DRAM clock
frequencies up to 533MHz need only 8 cycles for write recovery.
