In LS2080/LS2085, SFP is LE and Ver is 3.4
The base address is 0x01e80200
SFP will be used in Secure Boot to read fuses.

For ls2080, Added configs for various IPs used during secure boot

Added address and endianness for SEC and Security Monitor.

SRK - Fuses in SFP (Fused for public keys hash)
These are stored in LE format.

For Secure Boot, a header is used to identify key table, signature
and image address. For LS-CH3, there is a new header structure being used.

The following changes are there in the new header:
1) Currently IE Table (Key extension) feature is not supported
2) Single Key feature is not supported. Keys must be in table format.
3) Hence, SRK (Key table) is by default currently always present.
4) Max Key number has increase from 4 to 8. 8th Key is unrevockable.
5) New Barker Code is being used.

Following changes have been made to enable secure boot:
1) Sec_init has been called in starting to initialize SEC Block (CAAM)
which will be used for Secure Boot validation later for both ls2080a qds
and rdb
2) 64Bit address in ESBC Header has been enabled as this SoC is based on
armv8
3) Secure Boot defconfigs created for boards (NOR Boot).

During secure boot, Linux image along with other images are validated
using bootscript. This bootscript also needs to be validated before
it is executed. This requires a header for bootscript.

When secure boot is enabled, default bootcmd is changed to first validate
bootscript using the header and then execute the script.

For ls2080/5, NOR memory map is different from earlier arm SoCs.
So a new address on NOR is used for this bootscript header.
(0x583920000). The Bootscript address is mentioned in this header along
with addresses of other images.

During Secure Boot, a bootscript is validated using its header.
This patch copies both these images to DDR from NOR and then validates and
executed them from DDR. (If NOR is the boot source for LS2080 and LS2085).

This copy step is done to make this step common across booting sources.
Because in case of non-xip memories (e.g. NAND, SD) it is neccessary to copy
both these images to DDR.

For other ARM Platforms (ls1043 and ls1020), header is not copied from NOR
to DDR (otherwise customers will need to modify the existing headers).

Changes for v2:
	- for platform such as ls1043 and ls1021, boot header in NOR.
		Not copied to NOR. For them, fixed CONFIG_BOOTSCRIPT_HDR_ADDR
		to CONFIG_BS_HDR_ADDR_FLASH.

"fdt_high" env variable has been changed to 0xa0000000 for ls2080a
and ls2085a during Secure Boot. This env_varible is used to specify
the upper limit to be used for copying flat device tree.
This address must be visible to kernel.

The "fdt_high" value has been set during Secure Boot to same value
as it's default value during non-secure boot.

During secure boot, SMMU is enabled on POR by SP bootrom.
SMMU needs to be put in Bypass mode in uboot to
enable CAAM transcations to pass through.

During Nonsecure Boot, SP BootROM doesn't enable SMMU and
at reset SMMU is in bypass mode.

When MMU is disabled, 64bit Write must be at a memory aligned at
64bit Boundary. So, this commit splits the 64bit write into 2 -32bit
writes as the memory location is not guaranteed to be 64bit aligned.
The alignment exception only occurs when MMU is disabled.

To solve CAAM coherency issue on ls2080a and ls2085a.
When Caches are enabled and CAAM's DMA's AXI transcations are not
made cacheable, Core reads/write data from/to Caches and CAAM does from
Main Memory. This forces data flushes to synchronize various data structures
But even if any data in proximity of these structures is read by core,
these structures again are fetched in caches.

To avoid this problem, either all the data that CAAM accesses can be made
cache line aligned or CAAM transcations can be made cacheable.

So, this commit makes CAAM transcations as Write Back with Write and Read
Allocate.

For secure boot, currently we were using fixed bootargs for
all SoCs. This is not needed and we can use the bootargs
which are used in non-secure boot.
Incase bootargs are not defined for non-secure boot of any
platform, we use default bootargs.

In case of fatal failure during secure boot execution (e.g. header not found)
it is needed that the execution stops.
Earlier, we were asserting reset request in case in case of failure. But if
the RESET_REQ is not tied off to HRESET, this allows the execution to continue.

This can either be taken care in bootscript (Execute esbc_halt command in case of
image verification process) or it can be taken care in Uboot Code.

Doing the latter via a esbc_halt.

Currently, fsl_secboot_validate function used to set env variable "img_addr"
to contain address of image being validated.

The function has been changed to output image addr via argument
img_addr_ptr. The command esbc_validate sets the env variable
"img_addr".

This change helps when fsl_secboot_validate function is called from within
UBOOT (because now instead of calling function "getenv("img_addr")"
we can directly get the image address.)

  To: u-boot

For validating images from uboot (Such as Kernel Image), either keys
from SoC fuses can be used or keys from a veriied table of public keys
can be used. The latter feature is called IE Key Extension Feature.

For earlier SoCs, BootROM used to verify IE Key Table and then write the
address of this table in a secure register (SCRATCHREG). But in LS2088 and
LS2085, no such secure registers are available. Hence IE Table is left to be
verified by Uboot.

The new procedure is to first verify IE table using Keys stored in fuses,
and then use the keys in this table to verify further images. So the steps
are:

1) Verify IE Table (If "IE Table Flag" set in any image
i.e. Verify IE Table only when any image needs IE Table's Key to be verified)
2) Install IE table. (To be used across verification of multiple images.
Stored in a static global structure.)
3) If IE flag enabled in header of any image, Use keys from IE table,
otherwise use keys tied up with SoC's fuses (SRK).

The address of IE Table HDR is fixed for NOR. In case of boot from other
devices, IE Table and it's Header needs to be copied to an XIP Memory.

Changes for v2:
	- shifted glb struct in fsl_validate.c to .bss section from heap
	- freed struct fsl_secboot_img_priv in fsl_validate.c at end
	- for ie_table, using img addr return by fsl_secboot_validate function
		instead of using getenv("img_addr")
