TF-A Porting Guide
=================
@@ -64,3 +66,53 @@
- Please refer to '<path_to_mv_ddr_sources>/doc/porting_guide.txt' for detailed porting description.
- The build target directory is "build/<platform>/release/ble".
+ - Comphy Porting (phy-porting-layer.h or phy-default-porting-layer.h)
+ - Background:
+ Some of the comphy's parameters value depend on the HW connection between the SoC and the PHY. Every
+ board type has specific HW characteristics like wire length. Due to those differences some comphy
+ parameters vary between board types. Therefore each board type can have its own list of values for
+ all relevant comphy parameters. The PHY porting layer specifies which parameters need to be suited and
+ the board designer should provide relevant values.
+
+ .. seealso::
+ For XFI/SFI comphy type there is procedure "rx_training" which eases process of suiting some of
+ the parameters. Please see :ref:`uboot_cmd` section: rx_training.
+
+ The PHY porting layer simplifies updating static values per board type, which are now grouped in one place.
+
+ .. note::
+ The parameters for the same type of comphy may vary even for the same board type, it is because
+ the lanes from comphy-x to some PHY may have different HW characteristic than lanes from
+ comphy-y to the same (multiplexed) or other PHY.
+
+ - Porting:
+ The porting layer for PHY was introduced in TF-A. There is one file
+ ``drivers/marvell/comphy/phy-default-porting-layer.h`` which contains the defaults. Those default
+ parameters are used only if there is no appropriate phy-porting-layer.h file under:
+ ``plat/marvell/<soc family>/<platform>/board/phy-porting-layer.h``. If the phy-porting-layer.h exists,
+ the phy-default-porting-layer.h is not going to be included.
+
+ .. warning::
+ Not all comphy types are already reworked to support the PHY porting layer, currently the porting
+ layer is supported for XFI/SFI and SATA comphy types.
+
+ The easiest way to prepare the PHY porting layer for custom board is to copy existing example to a new
+ platform:
+
+ - cp ``plat/marvell/a8k/a80x0/board/phy-porting-layer.h`` "plat/marvell/<soc family>/<platform>/board/phy-porting-layer.h"
+ - adjust relevant parameters or
+ - if different comphy index is used for specific feature, move it to proper table entry and then adjust.
+
+ .. note::
+ The final table size with comphy parameters can be different, depending on the CP module count for
+ given SoC type.
+
+ - Example:
+ Example porting layer for armada-8040-db is under: ``plat/marvell/a8k/a80x0/board/phy-porting-layer.h``
+
+ .. note::
+ If there is no PHY porting layer for new platform (missing phy-porting-layer.h), the default
+ values are used (drivers/marvell/comphy/phy-default-porting-layer.h) and the user is warned:
+
+ .. warning::
+ "Using default comphy parameters - it may be required to suit them for your board".

The following build options are supported:
- ``ENABLE_STACK_PROTECTOR``: To enable the stack protection.
+
+
+Populate SD-card
+----------------
+
+The SD-card has to be formated with GPT.
+It should contain at least those partitions:
+
+- fsbl: to copy the tf-a-stm32mp157c-ev1.stm32 binary
+- ssbl: to copy the u-boot.stm32 binary
+
+Usually, two copies of fsbl are used (fsbl1 and fsbl2) instead of one partition fsbl.

+# OpenRISC assembly to turn off an ARM core on an Allwinner SoC from
+# the arisc management controller.
+# Generate a binary representation with:
+# $ or1k-elf-as -c -o turn_off_core.o turn_off_core.S
+# $ or1k-elf-objcopy -O binary --reverse-bytes=4 turn_off_core.o \
+# turn_off_core.bin
+# The encoded instructions go into an array defined in
+# plat/allwinner/sun50i_*/include/core_off_arisc.h, to be handed off to
+# the arisc processor.
+#
+# This routine is meant to be called directly from arisc reset (put the
+# start address in the reset vector), to be actually triggered by that
+# very ARM core to be turned off.
+# It expects the core number presented as a mask in the upper half of
+# r3, so to be patched in the lower 16 bits of the first instruction,
+# overwriting the 0 in this code here.
+# The code will do the following:
+# - Read the C_CPU_STATUS register, which contains the status of the WFI
+# lines of each of the four A53 cores.
+# - Loop until the core in question reaches WFI.
+# - Using that mask, activate the core output clamps by setting the
+# respective core bit in CPUX_PWROFF_GATING_REG (0x1f01500).
+# Note that the clamp for core 0 covers more than just the core, activating
+# it hangs the whole system. So we skip this step for core 0.
+# - Using the negated mask, assert the core's reset line by clearing the
+# respective bit in C_RST_CTRL (0x1f01c30).
+# - Finally turn off the core's power switch by writing 0xff to the
+# respective CPUx_PWR_SWITCH_REG (0x1f01540 ff.)
+# - Assert the arisc's own reset to end execution.
+# This also signals other arisc users that the chip is free again.
+# So in C this would look like:
+# while (!(readl(0x1700030) & (1U << core_nr)))
+# ;
+# if (core_nr != 0)
+# writel(readl(0x1f01500) | (1U << core_nr), 0x1f01500);
+# writel(readl(0x1f01c30) & ~(1U << core_nr), 0x1f01c30);
+# writel(0xff, 0x1f01540 + (core_nr * 4));
+# (using A64/H5 addresses)
