QEMU likes to have an MTRR set up, just like real machines. Add an MTRR
which covers the total RAM size.
This does nothing on machines without MTRRs.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present mtrr_add_request() requires that the size is a power of two.
This is too limiting for machines with 4GB (or more) of RAM, since they
often must take account of a memory hole at 3GB.
Update the function to automatically deal with an unaligned size, using
more MTRRs as required.

Rather than repeating the same code in several places, add some

Use the cpu_phys_address_size() function to obtain the physical-address

different value from the emulation CPU.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present it is not possible to find out the physical-address size in
long mode, so a predefined value is used.
Update the macros to support this properly, since it is important when

With the 64-bit descriptor we can use a jump instruction, rather than
pushing things on the stack.
Since the processor is in 64-bit mode by this point, pop a 64-bit value
from the stack, containing the target address.
This simplifies the code slightly, in particular its use of the stack.

At present it is not possible to execution 64-bit code without

The vesa display is widely used on hardware, but it is a bit of a pain
with QEMU. It requires executing option ROMs, which either doesn't work

THe bochs display is probably better anyway, so switch to that. It works

Check that the provided offsets are really pointing to a node

Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com>
Even though the RC node has the correct size and the ID mappings
are written to the end of the node, the ID 'mapping offset' and
'mapping count' are not written in the IORT RC node header, thus it
looks like that the RC node has no ID mappings.
The Linux kernel doesn't complain about the invalid IORT RC node,
even though the spec says that each RC node must have an ID mapping.
The kernel will fail to use MSI IRQs and fall back to a legacy IRQ
mechanism that's not working either.
Finally it will show strange behaviour around PCI interrupts, making it
hard to trace back to an invalid IORT RC nodes.
Add the missing ID mapping count and mapping offset.

Manorit Chawdhry <m-chawdhry@ti.com> says:
The series adds support for J742S2 family of SoCs. Also adds J742S2 EVM
Support and re-uses most of the stuff from the superset device J784s4.
This device is a subset of J784S4 and shares the same memory map and
thus the code is being reused from J784S4 to avoid duplication.
It initially cleans up the J784s4 and AM69 files so that they can be
re-usable for j742s2 and then it introduces J742S2.
The DT for the following SoC will be coming to U-boot during 6.13 Sync
so the series is kept as RFC till then.
Here are some of the salient features of the J742S2 automotive grade
application processor:
The J742S2 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration in automotive, ADAS and industrial
applications requiring AI at the network edge. This SoC extends the K3
Jacinto 7 family of SoCs with focus on raising performance and
integration while providing interfaces, memory architecture and compute
performance for multi-sensor, high concurrency applications.
Some changes that this devices has from J784S4 are:
* 4x Cortex-A72 vs 8x Cortex-A72
* 3x C7x DSP vs 4x C7x DSP
* 4 port ethernet switch vs 8 port ethernet switch
* 2 DDR controller vs 4 DDR controller
