The gpio_request_by_name() returns zero in case of success, however the
conditional return value check in gpio_request_by_name() checks only for
(ret != -ENOENT) and if the condition is true, returns ret outright.
This leads to a situation where successful gpio_request_by_name() return
leads to immediate successful eth_phy_of_to_plat() return as well, and
to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the
PHY driver operates with valid reset GPIO, but with assert/deassert times
set to default, which is 0, instead of the values from DT. This breaks
PHY reset.
Fix this by checking if return value is non-zero and then for this one
single allowed non-zero return value, -ENOENT.

tpm_tis_remove() leads to calling tpm_tis_ready() with the IO region
unmapped and chip->locality == -1 (locality released). This leads to a
crash in mmio_write_bytes().
The patch implements these changes:
tpm_tis_remove(): Unmap the IO region after calling tpm_tis_cleanup().
tpm_tis_cleanup(): Request locality before IO output and releasing

Sometimes UART stops transmitting characters after UART clock is changed
back to XTAL. In this state UART fifo is always full. Kernel during early
boot wants to print output on UART and is waiting for non-empty UART fifo.
Which leads to CPU hangup without any (debug) output on UART.
Marvell Armada 3700 Functional Specifications says that for programming
fractional divisor registers it is required to disable UART, enable
loopback mode, reset fifos, program registers, disable loopback mode,
release reset of fifos and enable UART.
But these steps do not fix above mentioned issue that UART hangup. Also
gating UART clock does not help. And even resetting UART state machines do
not help.
Experiments showed that UART fifo is unblocked after board is being reset
(during board reset UART HW transmit UART fifo even CPU is not executing
kernel/bootloader anymore).
And another experiments showed that same workaround can be achieved also
by external reset of UART HW (without need to reset board).
So do not implement any of "Marvell recommended" steps from Functional
Specifications as they do not work. And rather prior changing parent clock
back to XTAL, do external reset of UART HW. This operation also resets all
UART registers, so basically it also sets UART clock to default, which is
XTAL. It is unknown why UART hangups and enters such broken state.

There's a lot of code duplication in U-Boot right now. All the TPM TIS
compatible drivers we have at the moment have their own copy of a TIS
implementation.
So let's create a common layer which implements the core TIS functions.
Any driver added from now own, which is compatible with the TIS spec, will
only have to provide the underlying bus communication mechanisms.

Unfortunately, the device trees of all other layerscape SoCs are not

The driver will look for a named resource "ecc-addr", but this isn't the
official binding. In fact, the official device tree binding
documentation doesn't mention any resource names at all. But it is safe
to assume that it's the linux ones we have to use if we want to be
compatible with the linux device tree. Thus rename "ecc-addr" to
"sata-ecc" and convert all the users in u-boot.
While at it, also rename "sata-base" to "ahci" although its not used at
all.
