The DM driver for ockchip timer blocks is also applicable to the
RK3188 and RK3288 timer blocks: add 'rockchip,rk3188-timer' and
'rockchip,rk3288-timer' to its compatible list to support devices
claiming compatibility with these.

The generic ehci-driver (ehci-generic.c) will try to enable the clocks
listed in the DTSI. If this fails (e.g. due to clk_enable not being
implemented in a driver and -ENOSYS being returned by the clk-uclass),
the driver will bail our and print an error message.
This implements a minimal clk_enable for the RK3288 and supports the
clocks mandatory for the EHCI controllers; as these are enabled by
default we simply return success.

Throughput tests have shown the sunxi_mmc driver to take over 10s to
read 10MB from a fast eMMC device due to excessive delays in polling
loops.
This commit restructures the main polling loops to use get_timer(...)
to determine whether a (millisecond) timeout has expired. We choose
not to use the wait_bit function, as we don't need interruptability
with ctrl-c and have at least one case where two bits (one for an
error condition and another one for completion) need to be read and
using wait_bit would have not added to the clarity.
The observed speedup in testing on a A31 is greater than 10x (e.g. a
10MB write decreases from 9.302s to 0.884s).

With clang-4.0 and later we see:
warning: logical not is only applied to the left hand side of this bitwise
operator [-Wlogical-not-parentheses]
if ((!gd->flags & GD_FLG_RELOC))
^ ~
And while the compiler suggests adding parenthesis around gd->flags, a
reading of the code says that we want to know when GD_FLG_RELOC is not
set and then return.

The last clock consumer in SPL, SD/eMMC driver, gave up using the
clock driver. The clock driver is only used in U-Boot proper.
Signed-off-by: Masahiro Yamada <[email protected]>

The size of SPL is hitting the limit (64KB) for uniphier_v7_defconfig.
When booting from SD/eMMC, obviously its clock has been properly set up
by the boot ROM. Acutually, no need to re-initialize the clock in SPL.
Using a clock driver would generalize the SoC specific code, but
solving the memory footprint problem would win.

CONFIG_NAND_ZYNQ selects CONFIG_SYS_NAND_SELF_INIT, so the
driver doesn't have to play any ifdef game.
Also, we can mark zynq_nand_init() as static and get rid
of the mach-specific nand.h header.
This is really a revert of:
"mtd: zynq: nand: Move board_nand_init() function to board.c"

This driver is currently broken, refusing to initialize properly.
The reason is that get_nand_dev_by_index() was being called before
nand_register(), thus returning a pointer into uninitialized memory.
In other words, the struct mtd_info used by the driver is total junk.
Fix it by getting the correct struct mtd_info, via nand_to_mtd()
on the driver's struct nand_chip.
Tested on a custom board, where the CPU is halted without this patch.

U-boot driver for sunxi-mmc uses PLL6, unlike linux kernel where
PLL5 is used, with clock rates respectively 600MHz and 768MHz.
Thus there are different phase degree steps - 24 for the kernel and
30 for u-boot.
In the kernel driver the phase is set 90 deg for output and 120 for
sample. Dividing by 30 will result values 3 and 4. Those are the
values set in the u-boot driver.
However, the condition defining delays is wrong. MMC core driver
requests clock of 52MHz, sunxi-driver sets clock of 50MHz, but
phase is set 30 deg for output and 120 deg for sample.
Apparently this works for most cards.
On A20-SOM204-EVB-eMMC there is eMMC card (KLMAG2GEND) which complains
about it. Maybe there is other boards with similar problem?
So the fix is to match delays for both u-boot and kernel.
