2024-04-26rockchip: ringneck-px30: put STM32_RST line in input mode instead of outputQuentin Schulz
The STM32_RST line is routed to the ATtiny microcontroller PA0/RESET/UPDI pin. By driving the PX30 SoC pin as GPIO output high, we prevent external UPDI to be used for flashing without first putting this pin as GPIO input, an extra step we could avoid in userspace. There's an external hardware pull-up strong enough to keep the STM32_RST state high on ATtiny side but weak enough it can be overridden by external UPDI. This also means it is safe to use for the STM32 variant, where STM32_RST line will be in the same state as if output high was used. The Q7 standard specifies that MFG_NC1 and MFG_NC2 (used for UPDI for Ringneck) pins should neither be driven by the carrierboard, nor have pull-up or pull-down resistors. This means this commit is safe to use regardless of the carrierboard this module would be connected to (provided it follows the Q7 standard).

2024-04-26rockchip: spl: Cache boot source id for later useJonas Karlman
Rockchip BROM writes a boot source id at CFG_IRAM_BASE + 0x10, this id indicates from what storage media TPL/SPL was loaded from. SPL uses this id to determine what device "same-as-spl" represent when determining from where FIT should be loaded. This works as long as the boot_devices array contain a matching id <-> node path entry. However, SPL typically load a small part of TF-A into SRAM and on RK3399 this overwrites the CFG_IRAM_BASE + 0x10 addr used for boot source id. For affected devices the u-boot,spl-boot-device would not be set when booting from SPI flash and the flash@0 node was not explicitly listed in the u-boot,spl-boot-order prop. Here boot source id is 3 before FIT images is loaded, and 0 after: U-Boot SPL 2024.04-rc4 (Mar 15 2024 - 17:26:19 +0000) board_spl_was_booted_from: brom_bootdevice_id 3 maps to '/spi@ff1d0000/flash@0' Trying to boot from SPI ## Checking hash(es) for config config-1 ...

2024-04-26mmc: arm_pl180: Limit data transfer to U16_MAXMaximilian Brune
Currently fetching files bigger that cause a data transfer greater than U16_MAX fails. The reason is that the specification defines the datalength register as a 16 bit wide register, but in u-boot it is used as if it is an 32 bit register. Therefore values greater than U16_MAX cause an infinite loop inside u-boot. U-boot expects to get more data from interface/hardware then it will ever get and therefore inifintely waits for more data that will never come.

2024-04-26mmc: Support 32-bit only ADMA on 64-bit platformsGreg Malysa
Some arm64 platforms may include SDIO host controllers that only support 32-bit ADMA. While the Linux kernel detects which size is supported and adjusts the descriptor size used dynamically, the previous u-boot implementation statically selected between the two depending on whether DMA_ADDR_T_64BIT was defined. Because the static selection is already in place and effective for most platforms, this patch logically separates "64 bit addresses are used for DMA on this platform" and "64 bit addresses are used by the SDIO host controller for ADMA" in order to support the small number of platforms where these statements are not equivalent. Using 32 bits is opt-in and existing 64 bit platforms should be unaffected by this change.

2024-04-26mmc: sdhci: Fix potential ADMA descriptor table overflowIan Roberts
Change ADMA_TABLE_NO_ENTRIES to round the division up to fully contain CONFIG_SYS_MMC_MAX_BLK_COUNT, fixing potential buffer overflow of the ADMA descriptor table. sdhci_prepare_adma_table() expecitily states it does _not_ check for overflow as the descriptor table size is dependent on CONFIG_SYS_MMC_MAX_BLK_COUNT. However, the ADMA_TABLE_NO_ENTRIES calculation does not round up the divison, so with the current u-boot defaults: max_mmc_transfer = (CONFIG_SYS_MMC_MAX_BLK_COUNT * MMC_MAX_BLOCK_LEN) = 65535 * 512 = 33553920 bytes. ADMA_TABLE_NO_ENTRIES = max_mmc_transfer / ADMA_MAX_LEN = 33553920 / 65532, which does not divide cleanly. actual_max_transfer = ADMA_TABLE_NO_ENTRIES * ADMA_MAX_LEN = 512 * 65532 = 33552384, which is smaller than max_mmc_transfer. This can cause sdhci_prepare_adma_table() to write one extra descriptor, overflowing the table when a transaction larger than actual_max_transfer is issued.

Support is added for 5 new Qualcomm SoCs: * QCM2290 and SM6115 are low and mid range SoCs used on the RB1 and RB2 respectively. SM6115 is also used in some mid-range smartphones/tablets. Initial support includes buttons and USB (host and gadget). * SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship smartphones. The board can boot to a U-Boot prompt, but is missing regulators necessary for USB support. * SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024 respectively. Found on many high end smartphones. In addition: * Support is added for the Schneider HMIBSC board. * mach-snapdragon switches to OF_UPSTREAM * IPQ40xx gets several regressions fixed and some overall cleanup. * The MSM serial driver gains the ability to generate the bit-clock automatically, no longer relying on a custom DT property. * The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles don't need to be added). * Support for the GENI I2C controller is added. * The qcom SPMI driver has SPMI v5 support fixed, and v7 support added. * The qcom sdhci driver gets some fixes for SDCC v5 support. * SDM845 gains sdcard support * Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650) * SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs. * RB2 gets a work-around to fix the USB dr_mode property before booting Linux.

2024-04-23serial: msm: calculate bit clock dividerCaleb Connolly
The driver currently requires the bit clock divider be hardcoded in devicetree (or use the hardcoded default from apq8016). The bit clock divider is used to derive the baud rate from the core clock: baudrate = clk_rate / csr_div clk_rate is the actual programmed core clock rate which is returned by clk_set_rate(), and this UART driver only supports a baudrate of 115200. We can therefore determine the appropriate value for UARTDM_CSR by iterating over the possible values and finding the one where the equation above holds true for a baudrate of 115200. Implement this logic and drop the non-standard DT bindings for this driver. Tested on dragonboard410c. Tested-by: Robert Marko <[email protected]> Signed-off-by: Caleb Connolly <[email protected]>
