Merge patch series "Implement ACPI on aarch64"

2024-10-28T00:44:13+00:00

Patrick Rudolph  says:

Based on the existing work done by Simon Glass this series adds
support for booting aarch64 devices using ACPI only.
As first target QEMU SBSA support is added, which relies on ACPI
only to boot an OS. As secondary target the Raspberry Pi4 was used,
which is broadly available and allows easy testing of the proposed
solution.

The series is split into ACPI cleanups and code movements, adding
Arm specific ACPI tables and finally SoC and mainboard related
changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the
mandatory ACPI tables are supported, allowing to boot into Linux
without errors.

The QEMU SBSA support is feature complete and provides the same
functionality as the EDK2 implementation.

The changes were tested on real hardware as well on QEMU v9.0:

qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \
                    -pflash secure-world.rom \
                    -pflash unsecure-world.rom

qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \
-smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \
-dtb bcm2711-rpi-4-b.dtb -nographic

Tested against FWTS V24.03.00.

Known issues:
- The QEMU rpi4 support is currently limited as it doesn't emulate PCI,
  USB or ethernet devices!
- The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly
  cache related).
- PCI on RPI4 isn't working on real hardware since the pcie_brcmstb
  Linux kernel module doesn't support ACPI yet.

drivers: usb: Add generic XHCI

2024-10-27T23:24:13+00:00

Add support for the generic XHCI driver that contains no SoC
specific code. It can be used on platforms that simply work out
of the box, like on emulated platforms.

TEST: Booted on QEMU sbsa machine using the generic xhci driver.

usb: xhci: pet watchdog during transfers

2024-10-14T20:17:17+00:00

On some platforms with low USB throughput, tranfers
of huge files take a long time and watchdog timer can
expire resulting in hardware reset. Avoid this by
petting the watchdog as long as we have pending transfers.

Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.

Update the comment in bootstage to refer to this symbol, instead of
SPL_

phy: Extend generic_setup_phy() with PHY mode and submode

2024-09-09T15:18:04+00:00

Extend generic_setup_phy() parameter list with PHY mode and submode and
call generic_phy_set_mode() in generic_setup_phy(), so the generic PHY
setup function can configure the PHY into correct mode before powering
the PHY up.

Update all call sites of generic_setup_phy() as well, all of which are
USB host related, except for DM test which now behaves as a USB host
test.

Note that if the PHY driver does not implement the .set_mode callback,
generic_phy_set_mode() call returns 0 and does not error out, so this
should not break any existing systems.

usb: ehci-mx5: Add a default for CFG_MXC_USB_PORTSC

2024-08-31T01:46:52+00:00

Just like drivers/usb/host/ehci-mx6.c, add a default for
drivers/usb/host/ehci-mx5.c.

The motivation for doing this is to remove CFG_MXC_USB_PORTSC
from board config files.

All the mx5 boards, with the exeption of mx51evk, define
CFG_MXC_USB_PORTSC as:

 #define CFG_MXC_USB_PORTSC	(PORT_PTS_UTMI | PORT_PTS_PTW)

So move this definition as a default into ehci-mx5.c.
