Hi Tom and Lokesh,
I have been validating R5 on ZynqMP if u-boot is still working with
latest u-boot.
I found that you have added support for platform in subject. Can you
please tell me how you use u-boot on R5s?
Have you tried to run Linux on it too?
Thanks,
Michal
Xilinx ZynqMP R5 configuration is quite minimal and there is no reason to
enable EFI for it.

Map all resource for R5 to operate properly.
The patch is done based on the commit 23f7b1a77602 ("armv7R: K3: am654:
Enable MPU regions") which also map the whole 4GB at first and then change
mapping for DDR.

Even though we no longer call smp_function if an IPI was not sent by
U-Boot, we still need to clear any IPIs which were pending from the
execution environment. Otherwise, secondary harts will busy-wait in
secondary_hart_loop, instead of relaxing.

We can reduce the number of instructions needed to use available_harts_lock

This allows code to use a construct like `if (gd & gd->...) { ... }` when
accessing the global data pointer. Without this change, it was possible for
a very early trap to cause _exit_trap to read arbitrary memory. This could
cause a second trap, preventing show_regs from being printed.

Clearing MIP.MSIP is not guaranteed to do anything by the spec. In
addition, most existing RISC-V hardware does nothing when this bit is set.
The following commits "riscv: Use a valid bit to ignore already-pending

On the K210, the prior stage bootloader does not clear IPIs. This presents
a problem, because U-Boot up until this point assumes (with one exception)
that IPIs are cleared when it starts. This series attempts to fix this in a
robust manner, and fix several concurrency bugs I noticed while fixing

Some IPIs may already be pending when U-Boot is started. This could be a
problem if a secondary hart tries to handle an IPI before the boot hart has
initialized the IPI device.
This commit introduces a valid bit so secondary harts know when and IPI

Without a matching barrier on the write side, the barrier in handle_ipi
does nothing. It was entirely possible for the boot hart to write to addr,
arg0, and arg1 *after* sending the IPI, because there was no barrier on the
sending side.

Great idea Ulf.
We (Xerox Corp) load the FPGAs in uBoot because they have the PCIe
interface "hardware" and Linux comes up much easier if the PCIe
hardware exists and is operational on boot instead of attempting to
add it it later when Linux is up and you have to do a hot plug
install.
If we have
According to the mx25l12805d datasheet it supports using 4K or 64K sectors.
So lets add the SECT_4K to enable 4K sector usage.
