dd6df64c68 armv8: layerscape: rework spin table
There are two issues:

 (1) The spin table doesn't convert the endianness of the jump address.
     Although there is code for it, the result isn't used at all (x0).
 (2) If something goes wrong, the function returns. But that doesn't
     make sense at all.

Use the actual converted jump address as destination to fix. If
there is an error, jump to a trap loop. And rearrange the code exception
level switching code to make it smaller and clearer.

This reduces the size of the spin table code section from 696 bytes to
424 bytes. If CONFIG_ARMV8_SWITCH_TO_EL1 the code size reduced from 696
bytes to 632 bytes.

16863da82a armv8: layerscape: relocate spin table if EFI_LOADER is enabled
On ARM64, a 64kb region is reserved for the runtime services code.
Unfortunately, this code overlaps with the spin table code, which also
needs to be reserved. Thus now that the code is relocatable, allocate a
new page from EFI, copy the spin table code into it, update any pointers
to the old region and the start the secondary CPUs.

308deab9b1 armv8: layerscape: clean exported symbols in spintable.S
Add a new variable secondary_boot_code_start, which holds a pointer to
the start of the spin table code. This will help to relocate the code
section. While at it, move the size variable from the end to the
beginning so there is a common section for the variables. Remove any

b27f48540e armv8: layerscape: fix spin-table support
Spin tables are broken with bootefi. This is because - in contrast to
the booti call chain - there is no call to smp_kick_all_cpus(). Due to
this missing call the secondary CPUs are never released from their "wait
for interrupt state", see secondary_boot_func() in lowlevel.S.

Originally, this "wait for interrupt" is there to make sure, the spin
table is cleared before the secondary cores read it for the first time.
But the boot flow for the layerscape architecture is different from
that. The CPUs are release from their BootROM _after_ U-Boot's
spin-table is cleared, see fsl_layerscape_wake_seconday_cores() in mp.c.
Thus, there is no need to wait for this interrupt and no need for
kicking all cores on cpu_release. An atomic 64bit write to the
spin-table and a "sev" is sufficient.

a0018fc820 riscv: Make SiFive HiFive Unleashed board boot again
Commit 40686c394e ("riscv: Clean up IPI initialization code")
caused U-Boot failed to boot on SiFive HiFive Unleashed board.

The codes inside arch_cpu_init_dm() may call U-Boot timer APIs
before the call to riscv_init_ipi(). At that time the timer register
base (e.g.: the SiFive CLINT device in this case) is unknown yet.

It might be the name riscv_init_ipi() that misleads people to only
consider it is related to IPI, but in fact the timer capability is
provided by the same SiFive CLINT device that provides the IPI.
Timer capability is needed for both UP and SMP.

Considering that the original refactor does have benefits, that it
makes the IPI code more similar to U-Boot initialization idioms.
It also removes some quite ugly macros. Let's do the minimal revert
instead of a complete revert, plus a fixes to arch_cpu_init_dm() to
consider the SPL case.

Other than cpuinfo, reset cause can also be using during

The new rk3288 revision rk3288w has some changes with respect

So, add fdt board setup code to update cru compatible with

Currently 2.5 GB is calculated as DRAM size for a 1 GB RK322x board
if CONFIG_SPL_OPTEE is set. This is troublesome when booting a

gd->bd->bi_dram[0].start (which is basically CONFIG_SYS_SDRAM_BASE)
must not be taken into consideration for calculation of second bank
size, since this offset is already included in calculation of "top".

After applying this patch 992 MB (1024 MB - 32 MB reserved for

c372813105 mips: reloc: Change R_MIPS_NONE to catch pre-reloc BSS usage
This patch changes the R_MIPS_NONE define from 0 to a magic value. This
makes it possible to better detect any forbidden pre-relocation usage
of BSS variables, as they are often zero'ed and then relocation is
stopped too early.

Additionally the error message is improved to also print the faulting
address. This helps finding the root-cause for this breakage by
comparing this address with the values in System.map.

This patch helps a lot when working on pre-relocation code, like the
Octeon DDR init code, where such variables have hit me multiple times
now.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

b95611f67e x86: apl: Fix save/restore of ITSS priorities
The FSP-S changes the ITSS priorities. The code that tries to save it
before running FSP-S and restore it afterwards does not work as U-Boot
relocates in between the save and restore. This means that the driver
data saved before relocation is lost and the new driver just sees zeroes.

Fix this by allocating space in the relocated memory for the ITSS data.
Save it there and access it from the driver after relocation.

This fixes interrupt handling on coral.

Also drop the log_msg_ret() in irq_first_device_type() since this function
can be called speculatively in places where we are not sure if there is
an interrupt controller of that type. The resulting log errors are
confusing when there is no error.

3c41728d80 imx8m: Refactor the OPTEE memory removal
Current codes assume the OPTEE address is at the end of first DRAM bank.
Adjust the process to allow OPTEE in the middle of first bank.

When OPTEE memory is removed from first bank, it may split the first bank
to two banks, adjust the MMU table for the split case,
Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.

6036dba1c8 imx8m: disable nodes before kernel/mfgtool boot for fused part
To fused part, we need to disable nodes of dtb to let kernel boot.

To mfgtool, USB issue when using super-speed for mfgtool, temporally
work around the problem to use high-speed only.

2707faf01f imx8mn/imx8mp: override env_get_offset and env_get_location
To use one defconfig for all boot device, we have to runtime set
env offset and return env medium according to the boot device.
This patch overrides the env_get_offset and env_get_location to
implement the feature.

d1eee7eed9 imx8mp: Add fused parts support
iMX8MP has 6 fused parts in each qualification tier, with core, VPU,
ISP, NPU or DSP fused respectively.

The configuration tables for enabled modules:
MIMX8ML8DVNLZAA          Quad Core, VPU, NPU, ISP, DSP
MIMX8ML7DVNLZAA          Quad Core, NPU, ISP
MIMX8ML6DVNLZAA          Quad Core, VPU, ISP
MIMX8ML5DVNLZAA          Quad Core, VPU
MIMX8ML4DVNLZAA          Quad Lite
MIMX8ML3DVNLZAA          Dual Core, VPU, NPU, ISP, DSP

Add the support in U-Boot

2f3c92060d imx8m: workaround ROM serror
ROM SError happens on two cases:

1. ERR050342, on iMX8MQ HDCP enabled parts ROM writes to GPV1 register, but
when ROM patch lock is fused, this write will cause SError.

2. ERR050350, on iMX8MQ/MM/MN, when the field return fuse is burned, HAB
is field return mode, but the last 4K of ROM is still protected and cause
SError.

Since ROM mask SError until ATF unmask it, so then ATF always meets the
exception. This patch works around the issue in SPL by enabling SPL
Exception vectors table and the SError exception, take the exception
to eret immediately to clear the SError.
