- rti: support SPL (or re-start) (Alexander) - rti: drop hack manipulating WDT clock rate (Alexander)
2025-01-08Merge branch 'next'Tom Rini
2025-01-07watchdog: rti: drop hack manipulating WDT clock rateAlexander Sverdlin
The hack itself seems to be copied from Linux rti_wdt.c, but the WDT reset principle is different in U-Boot. While Linux relies on correct frequencies and timers and doesn't check the actual WDT counter value U-Boot driver seems to be more robust: it does compare RTIDWDCNTR vs RTIDWDPRLD. Now the root cause of the original motivation to manipulate the clock rate is said to be understood and fixed in Linux commit cae58516534e ("watchdog: rti_wdt: Set min_hw_heartbeat_ms to accommodate a safety margin") which simultaneously removed the hack itself. While is fix part of the mentioned patch is neither applicable nor requried for the U-Boot driver just drop the hack setting WDT clock rate to 90% of the real rate. This has a nice effect that the WDT timeout is now as requested and not 10% shorter.

2025-01-07watchdog: rti: support SPL (or re-start)Alexander Sverdlin
If the RTI watchdog has been enabled in SPL, enabling it in U-Boot proper fails because it can only be enabled once in HW and never stopped. This however leads to a situation that wdt_cyclic() watchdog trigger is not being started any longer and the WDT fires at some point. Allow for WDT re-start by not bailing out if the [previously] configured period matches the one to be configured. Enabling in [A53] SPL has been tested on AM62x-based HW (where [A53] SPL is responsible for loading R5 DM firmware and not this driver).

2025-01-01Revert "net: phy: marvell 88e151x: Fix handling of bare RGMII interface type"Rufus Segar
This reverts commit 431be621c6cbc72efd1d45fa36686a682cbb470a. Section 3.3 of Reduced Gigabit Media Independent Interface (RGMII) Version 2.0 (4/1/2002) details that a PHYs using a ~2ns internal delay are referred to as RGMII-ID. This internal delay is optional. Page 147-148 of the Marvell Doc. No. MV-S107146-U0 Rev. F details timings of the RX/TX delays. We see that with the TX/RX_CLK delay enabled, our RX/TX_CTL signal is shifted w.r.t CLK to reflect the delay added. In 431be62 there is no timing difference between RGMII and RGMII-ID, and so programmers wanting to explicitly set their PHY to RGMII will find that delay added anyway. This could throw off timing if that internal delay is undesired. We should be handling all 4 possible RGMII cases of PHY_INTERFACE_MODE: RGMII, RGMII_ID, RGMII_TXID, and RGMII_RXID. Reverting 431be62 implements this. See also m88e1111_config_init_rgmii_delays in the equivalent driver in Linux (drivers/net/phy/marvell.c), which does not set these delays in RGMII mode. 68e6eca was tested out on an 88E1512 PHY in RGMII-ID mode. This reversion has been tested by myself on an 88E1518 in RGMII-ID mode. This patch affects boards using this driver in "rgmii" mode, as the internal delay will no longer be enabled. Namely kikwood-nsa310s. Signed-off-by: Rufus Segar <rhs@riseup.net>

2024-12-30gpio: mpc8xxx: Preserve pre-init state of outputsJ. Neuschäfer
The mpc8xxx_gpio driver contains a workaround for certain chips where the previously written state of outputs cannot be read back from the GPIO data (GPDAT) register (MPC8572/MPC8536). This workaround consists of tracking the state of GPDAT in a "shadow register" (i.e. a software variable). The shadow register is initialized to zero. This results in a problem w.r.t. outputs that are configured to a high (1) state before U-Boot runs, but not touched by U-Boot itself: Due to the zero-initialization, these GPIOs end up being set to zero, the first time that any other output is set. To avoid such issues initialize the GPDAT shadow register to the value previously held by any outputs, if possible. On MPC8572/MPC8536 this should make no difference, i.e. the shadow register should be initialized to zero on these chips. This patch has been tested on a MPC8314E-based board.

2024-12-29remoteproc: renesas: Add Renesas R-Car Gen4 remote processor driverMarek Vasut
Add R-Car Gen4 APMU controller remoteproc driver capable of starting the Cortex-R52 cores in Renesas R8A779G0 V4H/V4M SoC. The APMU IP is in fact a power management unit capable of additional operations, but those are not used by U-Boot so far. This requires slight adjustment to the SPL entry point code, as that is being executed on the Cortex-R52 #0 and the Cortex-R52 #0 enters an endless loop once it starts the rest of the SPL on Cortex-A76 core. The endless loop now checks for content of APMU CRBARP registers and tests whether valid VLD_BARP and BAREN_VALID bits are set, if so, the Cortex-R52 core exits the endless loop and jumps to address started in CRBARP[31:18] register in ARM mode, which is a trampoline code to jump to the final entry point. The trampoline code is in place to avoid limitation of CRBARP[31:18] address field, which limits the core start address to memory addresses aligned to 0x40000 or 256 kiB . The trampoline is placed at 0x40000 aligned address and jumps to the final entry point, which can be at an address with arbitrary alignment at instruction granularity.

In case no PFC table matches the SoC in use, do not probe the driver and instead exit with -ENODEV. This should never happen under normal conditions, because this would mean the driver DT compatible string match happened, but the list in probe() cannot match the model listed in match data associated with the compatible string on which the match did happen.
