e8bb990fe7 ARM: imx8m: fix imx_eqos_txclk_set_rate() type mismatch for LTO
When building imx8mp_evk_defconfig with LTO, the compiler complains
about type mismatch of function imx_eqos_txclk_set_rate() in file
  drivers/net/dwc_eth_qos.c:845:12
which contains a weak definition of this function, vs file
  arch/arm/mach-imx/imx8m/clock_imx8mm.c
which contains an implementation.

Change the type of this function in the implementation to fix this.

86c5e21013 ARM: make gd a function call for LTO and set via set_gd()
On ARM, the gd pointer is stored in registers r9 / x18. For this the
-ffixed-r9 / -ffixed-x18 flag is used when compiling, but using global
register variables causes errors when building with LTO, and these
errors are very difficult to overcome.

Richard Biener says [1]:
  Note that global register vars shouldn't be used with LTO and if they
  are restricted to just a few compilation units the recommended fix is
  to build those CUs without -flto.

We cannot do this for U-Boot since all CUs use -ffixed-reg flag.

It seems that with LTO we could in fact store the gd pointer differently
and gain performance or size benefit by allowing the compiler to use
r9 / x18. But this would need more work.

So for now, when building with LTO, go the clang way, and instead of
declaring gd a global register variable, we make it a function call via
macro.

2fc93e5baf imx: bootaux fix elf loading
This reverts the arch/arm/mach-imx/imx_bootaux.c changes of commit
805b3cac1e. The loader function name was changed so that it does
not clash with the generically available function in lib/elf.c.

imx-bootaux loads an elf file linked for an auxilary core. Thus the
loader function requires address translation from the auxilary core's
address space to where those are mapped into U-Boot's address space.

So the elf loader is specific and must not be replaced with a generic
loader which doesn't provide the address translation functionality.

Fixes commit 805b3cac1e ("lib: elf: Move the generic elf
loading/validating functions to lib")

Calling csf_is_valid() with an un-signed image may lead to data abort
as the CSF pointer could be pointing to a garbage address when accessed
in HAB_HDR_LEN(*(const struct hab_hdr *)(ulong)ivt_initial->csf).

To avoid such errors during authentication process, validate IVT structure
by calling validate_ivt function which checks the following values in an IVT:

IVT_HEADER = 0x4X2000D1
ENTRY != 0x0
RES1 = 0x0
DCD = 0x0       /* Recommended */
SELF != 0x0     /* Absoulute address of IVT */
CSF != 0x0
RES2 = 0x0

This commit also checks if Image's start address is 4 byte aligned.

commit "0088d127 MLK-14945 HAB: Check if IVT valid before authenticating image"
removed as this patch addresses the issue.

507da978fa imx: HAB: Update hab codes to support ARM64 and i.MX8M
There are some changes to support ARM64 i.MX8M platform in this patches:
1. The hab_rvt base and function vectors are different as i.MX6/7

2. Need to bypass an workaround for i.MX6 to fix problem in MMU.

3. The x18 register needed save & restore before calling any HAB API. According
   to ARM procedure call spec, the x18 is caller saved when it is used as
   temporary register. So calling HAB API may scratch this register, and
   cause crash once accessing the gd pointer.

   On ARMv7, the r9 is callee saved when it is used as variable register. So
   no need to save & restore it.

4. Add SEC_CONFIG fuse for iMX8M

When current EL is not EL3, the direct calling to HAB will fail because
CAAM/SNVS can't initialize at non-secure mode. In this case, we use
SIP call to run the HAB in ATF.

c428ca80c2 imx: hab: Add function to authenticate kernel image
When loading kernel image, the image size is parsed from header, so it
does not include the CSF and IVT.

Add back the authenticate_image function to wrap the imx_hab_authenticate_image
with calculating IVT offset and full image size.

function sec_in32() is reading CAAM registers and if CAAM clock is disabled
the system will hang.

30e39ac7c9 imx: imx7 Support for Manufacturing Protection
This code was originally developed by Raul Cardenas <raul.casas@nxp.com>
and modified to be applied in U-Boot imx_v2017.03.

More information about the initial submission can be seen
in the link below:
https://lists.denx.de/pipermail/u-boot/2016-February/245273.html

i.MX7D has an a protection feature for Manufacturing process.
This feature uses asymmetric encryption to sign and verify
authenticated software handled between parties. This command
enables the use of such feature.

The private key is unique and generated once per device.
And it is stored in secure memory and only accessible by CAAM.
Therefore, the public key generation and signature functions
are the only functions available for the user.

The manufacturing-protection authentication process can be used to
authenticate the chip to the OEM's server.

Command usage:

Print the public key for the device.
- mfgprot pubk

Generates Signature over given data.
- mfgprot sign <data_address> <data_size>
