This patch intends to remove all code which enables hardware read
leveling. We need to disable h/w read leveling because new ASV table
is merged in kernel (which is based on the new characterization
condition) and new characterization environment has h/w read leveling
disabled, so we should also disable this. Also, disabling h/w read
leveling improves the MIF LVcc value (LVcc value is the value at which
DDR will fail to work properly), improve LVcc means we have enough
voltage margin for MIF. When h/w leveling is enabled, we have almost
zero volatge margin.

This patch moves around some of the existing Exynos5 USB 2.0 PHY code
to make it cleaner in preparation of the 3.0 PHYs. It moves the VBUS
GPIOs (which are completely board-specific) into the mainboard code and
makes sure to only initialize PHYs on the boards that actually need
them. It also removes the USB 3.0 PLL hack that was needed on Snow from
the Pit and Kirby boards (which do not have that PLL anymore).

The USB bulk and control transfer functions in libpayload currently
always return 0 for success and 1 for all errors. This is sufficient for
current use cases (essentially just mass storage), but other classes
(like certain Ethernet adapters) need to be able to tell if a transfer
reached the intended amount of bytes, or if it fell short.
This patch slightly changes that USB API to return -1 on errors, and the
amount of transferred bytes on successes. All drivers in the current
libpayload mainline are modified to conform to the new error detection
model. Any third party users of this API will need to adapt their
if (...<controller>->bulk/control(...)) checks to
if (...<controller>->bulk/control(...) < 0) as well.
The host controller drivers for OHCI and EHCI correctly implement the
new behavior. UHCI and the XHCI stub just comply with the new API by
returning 0 or -1, but do not actually count the returned bytes.

As per hardware recommendation, CKE PAD retention release must
happen just before gate leveling enable and only in case of resume.
Hence, this patch moves pad retention release from dmc_common.c to
dmc_init_ddr3_exynos5420.c. In addition to this we are providing
125 (+3 extra being safe) times auto refresh to DRAM by sending
REFA direct command. This is required because when CKE PAD retention
release happens, self refresh mode of DDR3 is disabled.
Hence, auto refresh 125 times.
This is ported from https://gerrit.chromium.org/gerrit/#/c/65573
Note: Since WAKEUP_DIRECT does not go thru memory init, it should be
safe to move CKE PAD retention out of bootblock.c.

Apparently the IROM doesn't like data caches... the recently added
dcache-in-bootblock makes A-A booting fail, and flushes/invalidations
alone don't seem to fix it. It's pretty fast anyway, so we just disable
the cache again for the duration of the IROM call.
Also removes a superfluous invalidation line from the bootblock code...
dcache_mmu_enable/disable already take care of that.

snow and pit: turn on FET4 (for SD card) at bootup
Explictly enable FET4 on Snow and Pit.
Historically we haven't needed to do this because:
* On snow there's a bypass around FET4 which effectively eliminates
it. Even if we don't turn on FET4 the SD card is still powered.
Turning on FET4 doesn't hurt though and is technically correct.
* On pit the EC turns on FET4 on cold bootup.
On pit we run into a problem if the kernel turns off FET4 like in
<https://gerrit.chromium.org/gerrit/#/c/65332/> and then we get a
software reset or warm reset. In this case the EC won't know to turn
it back on.

The current XHCI code only sets IOC on the last TRB of a TD, and
doesn't set ISP anywhere. On my Synopsys DesignWare3 controller, this
won't generate an event at all when we have a short transfer that is not
on the last TRB of a TD, resulting in event ring desync and everyone
having a bad time. However, just setting ISP on other TRBs doesn't
really make for a nice solution: we then need to do ugly special casing
to fish out the spurious second transfer event you get for short
packets, and we still need a way to figure out how many bytes were
transferred. Since the Short Packet transfer event only reports
untransferred bytes for the current TRB, we would have to manually walk
the rest of the unprocessed TRB chain and add up the bytes. Check out
U-Boot and the Linux kernel to see how complicated this looks in
practice.
Now what if we had a way to just tell the HC "I want an event at exactly
*this* point in the TD, I want it to have the right completion code for
the whole TD, and to contain the exact number of bytes written"? Enter
the Event Data TRB: this little gizmo really does pretty much exactly
what any sane XHCI driver would want, and I have no idea why it isn't
used more often. It solves both the short packet event generation and
counting the transferred bytes without requiring any special magic in
software.

On ARM platforms the TPM is not attached through LPC but through I2C.
This patch adds an I2C TPM driver that supports the following chips:
* Infineon SLB9635
* Infineon SLB9645
In order to select the correct TPM implementation cleanly, CONFIG_TPM
is moved to src/Kconfig and does the correct choice.

i2c tpm: Remove mostly useless delay code/tables.
I assume from the code in the TPM driver that the TPM spec defines
different types of delays and timeouts which each have a particular
duration, and that the TPM can tell you how long each type is if you ask
it. There was a large table, some members of a data structure, and a
function or two which managed the timeouts and figured their value for
different operations. The timeout values for the various "ordinals"
were never set in the vendor specific data structure, however, and
always defaulted to 2 minutes. Similarly the timeouts a, b, c, and d
were never overridden from their defaults. This change gets rid of all
the timeout management code and makes the "ordinal" timeout 2 minutes
and the a, b, c, and d timeouts 2 seconds, the larger of the two default
values.
This is a port from depthcharge to coreboot, original change:

TPM: Stop requesting/releasing the TPM locality.
The locality is requested when the TPM is initialized and released when
it's cleaned up. There's no reason to set it to the same thing again and
restore it back to the same value before and after every transaction.

We were running this loop 100 times with 5 ms delays. Change it
to run 500 times with 1 ms delays, which gives us the same
overall timeout but lets us bail out a bit sooner -- in practice,
at most, 4 ms sooner but every bit counts. Note, however, that
the tighter timing does reduce opportunities for threading. There
is a non-obvious set of tradeoffs on timeouts.

This patch enhances the armv7 exception handlers in Coreboot and
libpayload to show the correct SP and LR registers from the aborted
context, and also dump a part of the current stack. Since we cannot
access the banked registers of SVC mode from a different exception mode,
it changes Coreboot (and its payloads) to run in System mode instead. As
both modes can execute all privileged instructions, this should not have
any noticeable effect on firmware operation (please correct me if I'm
wrong!).
