When running on SoC with multiple clusters, the boot CPU may
not be fixed, saying booting from cluster A or cluster B.
Add a API that can return the udevice for current boot CPU.
Cpu driver needs to implement is_current_cpu interface for this
feature, otherwise the API only returns the first udevice in
cpu uclass.

This patch adds a "bulk" API to the phy API in order to
get/init/exit/power on/off a group of phys associated
with a device.
The bulk API will avoid adding a copy of the same code to
manage a group of phys in drivers.

Move CONFIG_SYS_ARM_CACHE_WRITETHROUGH and
CONFIG_SYS_ARM_CACHE_WRITEALLOC into Kconfig done by moveconfig.py.
Kconfig uses a choice between the 3 values supported in U-Boot,
including the new configuration CONFIG_SYS_ARM_CACHE_WRITEBACK
(the default configuration).

define FEC_ENET_ENABLE_TXC_DELAY to enable the delay on TXC line on
the MAC. This has to be done in order to meet RGMII specs.
According to RGMII specs the clock should get delayed so the edges of
the clock are preferrably in the middle of the edges of data-lines so
they can be sampled properly.
Our PHY expects the MAC to delay TXC line, as it is also written
in the spec. This patch makes sure the TXC delay on the FEC is enabled

This patch adds skew register settings for KSZ9131. It checks first
which phy is on the board and then applies the correct skew settings.
Skew settings calculation for the KSZ9131:
The i.MX6 SoC has an output skew tolerance of -100ps to 900ps. All
PCB traces where routed exactly the same length so we can calculate
the skew settings without taking the length into consideration. The
traces are all length matched.
RXC skew (PHY to MAC):
- We use the 2ns DLL controlled delay on the PHY
- We do not use the skew registers
This results in the following values:
RXC
PHY fixed Delay 2000ps
PHY Added Delay 0ps
T_setup_R min 2.00ns
T_setup_R typ 2.00ns
T_setup_R max 2.00ns
T_hold_R min 1.60ns
T_hold_R typ 2.00ns
T_hold_R max 2.40ns
That means we are well within RGMII specs.
TXC skew (MAC to PHY):
- We use the 2ns DLL controlled delay on the PHY
- We then subtract ~0.6ns with TXD[0:3] and TXC clock pad skew
register in a resulting ~1.4ns delay.
This results in the following values under consideration of the
tolerances:
TXC min TXC typ TXC max
MAC min -100ps -100ps -100ps
MAC max 900ps 900ps 900ps
PHY fixed Delay 2000ps 2000ps 2000ps
PHY added Delay -340ps -600ps -859ps
T_setup_T min 1.56ns 1.30ns 1.04ns
T_setup_T typ 2.06ns 1.80ns 1.54ns
T_setup_T max 2.56ns 2.30ns 2.04ns
T_hold_T min 1.04ns 1.30ns 1.56ns
T_hold_T typ 1.94ns 2.20ns 2.46ns
T_hold_T max 2.84ns 3.10ns 3.36ns
This shows that T_hold_T min and T_setup_T min times are out of spec
for RGMII timing. However the KSZ9131 has a minimal value for this time
of 0.8ns which is met under all circumstances.

Move this code to a generic location so that we can test it with sandbox.
This requires adding a few new fields to acpi_ctx, so drop the local

Also use mapmem to avoid pointer-to-address casts which don't work on
sandbox.

The current code uses an address but a pointer would result in fewer
casts. Also it repeats the alignment code in a lot of places so this would
be better done in a helper function.

Probe the FMan MACs based on the device tree while
retaining the legacy code/functionality.
One notable change introduced here is that, for DM_ETH,
the name of the interfaces is corrected to the fmX-macY
format, that avoids the referral to the MAC block names
which were incorrect for FMan v3 devices (i.e. DTSEC,
TGEC) and had weird formatting (i.e. FM1@DTSEC6, FM1@TGEC1).
The legacy code is left unchanged in this respect.
