8f01397ba7 powerpc/mpc85xx: SECURE BOOT- Enable chain of trust in SPL
As part of Chain of Trust for Secure boot, the SPL U-Boot will validate
the next level U-boot image. Add a new function spl_validate_uboot to
perform the validation.

Enable hardware crypto operations in SPL using SEC block.
In case of Secure Boot, PAMU is not bypassed. For allowing SEC block
access to CPC configured as SRAM, configure PAMU.

f698e9f39a powerpc/SECURE_BOOT: Add PAMU driver
PAMU driver basic support for usage in Secure Boot.
In secure boot PAMU is not in bypass mode. Hence to use
any peripheral (SEC Job ring in our case), PAMU has to be
configured.

The patch reverts commit 7cad2e38d6.

The Header file pamu.h and few functions in driver have been derived
from Freescale Libos.

43381474ff arch/powperpc: Fix start_align due to use of __ffs64() instead ffs64()
Incorrect DDR law was created in case of B4860qds after commit
2d2f490d. Return value of ffs64() differs from __ffs64(), eg.
    ffs64(0x80000000) = 0x20
    __ffs64(0x80000000) = 0x1f
As a result of this change, callers need to adjust the expected
return value by removing -1.

da58dec866 Various Makefiles: Add SPDX-License-Identifier tags

Makefiles are worth adding SPDX-License-Identifier tags too, and most of

It will make u-boot recognize all non-ppc cores and peripherals like
SC3900/DSP CPUs, MAPLE, CPRI and print their configuration in u-boot logs.

b539534d12 PPC 85xx QEMU: Always assume 1 core
We only need u-boot to bother about a single core in the QEMU machine.
Everything that would require additional knowledge of more cores gets
handled by QEMU and passed straight into the payload we execute.

Because of this setup, it would be counterproductive to enable SMP support
in u-boot. We would have to rip CPUs out of already existing spin tables
and respin them from u-boot. It would be a pretty big mess.

So only assume we have a single core. This fixes errors about CONFIG_MP
being disabled.

The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)'
is weird.
kbdg.o is not included in $(OBJS) but linked into $(LIB)
and $(LIB) is not dependent on kgdb.o.
(Broken dependency tracking)

So,
    START   = start.o kgdb.o
shoud have been
    START   = start.o

The code from the internal on-chip ROM. It loads the final uboot image
into DDR, then jump to it to begin execution.

The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
	* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
	ddr spd code can get the interleaving mode setting in env. It loads
	final uboot image from offset 96KB.
	* final uboot image, size is variable depends on the functions enabled.

c63e137014 powerpc/mpc8xxx: Add memory reset control
JEDEC spec requires the clocks to be stable before deasserting reset
signal for RDIMMs. Clocks start when any chip select is enabled and
clock control register is set. This patch also adds the interface to
toggle memory reset signal if needed by the boards.

b61e061566 powerpc/mpc8xxx: Add x4 DDR device support
On selected platforms, x4 DDR devices can be supported. Using x4 devices may
lower the performance, but generally they are available for higher density.

Tested on MT36JSF2G72PZ-1G9E1 RDIMM.

d8556db1d4 powerpc/mpc8xxx: Set inactive csn_bnds to 0xffffffff
When chip select interleaving is enabled, cs0_bnds is used for address
binding. Other csn_bnds are not used. When two controllers interleaving is
enabled, cs0_bnds of both controllers are used, other csn_bnds are not.
However, the unused csn_bnds may be used internally for calculating
addresses for calibration. Setting those registers to 0 may confuse
controllers in some cases. Instead, setting them to 0xffffffff together
with normal LAWs will guarantee the address is not mapped to DDR.

cb93071bb6 mpc85xx: Base emulator support
Prepare for emulator support for mpc85xx parts.
Disable DDR training and skip wrlvl_cntl_2 and wrlvl_cntl_3 registers.
These two registers improve stability but not supported by emulator.
Add CONFIG_FSL_TBCLK_EXTRA_DIV for possible adjustment to time base.

362ee04b79 fsl_ifc: add support for different IFC bank count
Calculate reserved fields according to IFC bank count

1. Move csor_ext register behind csor register and fix res offset
2. Move ifc bank count to config_mpc85xx.h to support 8 bank count
3. Guard fsl_ifc.h with CONFIG_FSL_IFC macro to eliminate the compile
   error on some devices that does not have IFC controller.

c8b281524b powerpc/boot: Change the macro of Boot from SRIO and PCIE master module
Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable
the master module of Boot from SRIO and PCIE on a platform. But this
is not a silicon feature, it's just a specific booting mode based on
the SRIO and PCIE interfaces. So it's inappropriate to put the macro
into the file arch/powerpc/include/asm/config_mpc85xx.h.

Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to
"CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from
arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros
in configuration header file of each board which can support the
master module of Boot from SRIO and PCIE.

Allow DDR clock runs faster than SPD specifes. This may cause memory
failure, but the user should know what is going to happen when using
higher than expected DDR clock.

f69814397e powerpc/chassis2: Change core numbering scheme
To align with chassis generation 2 spec, all cores are numbered in sequence.
The cores may reside across multiple clusters. Each cluster has zero to four
cores. The first available core is numbered as core 0. The second available
core is numbered as core 1 and so on.

Core clocks are generated by each clusters. To identify the cluster of each
core, topology registers are examined.

Cluster clock registers are reorganized to be easily indexed.

Generation 2. The major difference between T1040 and its variants is the
