David Hendricks 1ad77de62d exynos5420: Assign corect parent PLLs
Assign correct parent PLL's for the following clocks:
ACLK_400_WCORE (MPLL->CPLL) (400 -> 333MHz)
PCLK_200_FSYS (MPLL->DPLL) (200 -> 200MHz)
MUX_ACLK_100_NOC_SEL (MPLL -> DPLL) (100 -> 100MHz)
ACLK_266 (DPLL->MPLL) (300 -> 266MHz)
ACLK_200_DISP1(MPLL->DPLL) (200 -> 200MHz)
ACLK_400_MSCL(MPLL->CPLL) (400 -> 333MHz)
ACLK_66 (MPLL->CPLL) (66.666 -> 66.6MHz)
MUX_ACLK_400_DISP1_SEL (CPLL->DPLL) (666 -> 300MHz)
MUX_MPHY_REFCLK (MPLL->OSC)
MUX_UNIPRO (MPLL->OSC)
MUX_MIPI1 (EPLL->OSC)
MUX_DP1_EXT_VID (EPLL->OSC)
MUX_FIMD1_OPT (EPLL->OSC)
MUX_IPLL(IPLL->OSC)
This also corrects the clock dividers for few of the clocks,
as the clock parent changes affect the final frequency of the
clocks.

David Hendricks 7f35bbb0d4 exynos5420: don't assume MPLL for i2c parent clock
This reads the clock select field for MUX_ACLK_66_SEL in the
CLK_SRC_TOP1 register in order to obtain the source clock rate
for I2C peripherals. Before we were always assuming that the source
was the MPLL.

Unfortunately not all fields in the CLK_SRC_TOPn registers are
enumerated the same with regard to clock select. So this is just
a one-off for now.

This is basically ported from https://gerrit.chromium.org/gerrit/#/c/62443.

David Hendricks 401da25827 exynos5420: re-factor clock_get_periph_rate()
This re-factors clock_get_periph_rate() to be a simpler and also
make a few corrections along the way. To summarize:

- clk_bit_info is no longer used. It had numerous errors and was
  really painful anyway since it was just a bunch of opaque magic
  numbers that made bugs non-obvious.

- Clock source bitfields for peripherals handled in the switch
  statement are 3 bits, not 4. Some divider values are 3 bits,
  some are 4. The earlier code always assumed 4 bits for both
  which included reserved bits in many cases.

- UART source clock and divider shift values were wrong.

- PWM clock divider was being read from the wrong register.

- SPI3 divider value was being read from the wrong register.

- There was a really confusing calculation for SDMMC0 and SDMMC2
  clock rates, but it was never actually used since the switch
  statement never handled PERIPH_ID_SDMMC{0,2} and would thus
  return if they were ever passed into this function.

David Hendricks efd4b9e936 exynos5420: add a peripheral clock select --> PLL decoder
This adds a helper function to translate between peripheral clock
select fields in clock source registers and PLLs. Some of this was
already done to handle a few special cases, this generalizes the
earlier work so that follow-up patches can do further clean-up.

Unfortunately, the PLLs represented by clock select fields in
various modules are not uniformly ordered. So for now we focus on
peripheral clock sources only.

Julius Werner ce011ec131 exynos5250: Implement support to boot with USB A-A firmware upload
This patch implements the basic infrastructure required to use the USB
A-A firmware upload feature on Exynos5 processors with Coreboot. It will
require a corresponding host-side script that activates the feature and
uploads the correct image parts in the correct order to harcoded target
addresses, as described in the comments of alternate_cbfs.c.

Also fixes a bug in the Google Snow mainboard where it would not
correctly initialize the pinmux configuration for the SPI flash bus.
During a normal SPI boot the IROM would already do that for you, but
when booting from USB you have to do it yourself.

David Hendricks e0cfad2b56 exynos5420: re-factor the SDMMC GPIO config routines
The existing GPIO config routines for SDMMC0-2 are over-generalized
and somewhat confusing as a result. It would work nicely if all SDMMC
ports were configured in the same fashion, but there are a few
exceptions.

For example, the inner function runs differently if we're using 8 bits
of data instead of 4, so a big chunk is skipped for SDMMC2. SDMMC0
requires SD_0_CDn to be an output rather than alternate function and
must have a value set.

This patch trades some verbosity for simplicy. Now the SDMMC GPIO
configuration a straight-forward sequence of GPIO operations
without any exceptions.

Ronald G. Minnich c0d5eb2a33 Pit: graphics
This includes the new dp code, which is better, and the fimd code,
which is changed and improved. We took the chance to remove un-needed
files, and also to remove some foolish u-boot habits, but not all of
them. That will take time.

With these changes we get graphics.

Since the only mainboards we have with 16 bit graphics are 5:6:5,
adjust edid.c to just use that format. If at some future time we need
4:4:4, which seems unlikely, we'll need to add a function to adjust
the lb_framebuffer. Note that you can't just divine this from the EDID,
as the graphics pipe format need not match the actual final format used.

The EDID reading works. We've been requested to support hard-coded
EDIDs and that will come in the next revision. Currently the hard-coded
EDID is ignored for testing.

Gabe Black aa6061a0d0 kirby: pit: Fix up wakeup_need_reset
In a previous commit the contents of wakeup_need_reset were removed because
the GPIO it referred to wasn't connected to anything on pit. I didn't realize
at that time that that could have been because we hadn't tried getting
suspend/resume working on pit and hadn't updated that file. On snow, the GPIO
is the recovery mode pin. This change updates pit to have the right GPIO,
kirby to read that GPIO, and makes the comments for both pit and kirby more
explicit and spells out the fact that this is the recovery mode GPIO.

Having a check here at all may still be a holdover from snow that isn't
applicable to pit or kirby, but since there is a parallel as far as the
recovery mode GPIO we might as well make them match while waiting for more
information.
