RISC-V soc driver fixes for v6.13-rc4 A single fix for the Auto Update driver, where a mistake in array indexing (accessing as a u32 rather than a u8) caused the driver to read the wrong feature disable bits.

efi/zboot: Limit compression options to GZIP and ZSTD

2024-12-06T15:59:56Z

For historical reasons, the legacy decompressor code on various architectures supports 7 different compression types for the compressed kernel image. EFI zboot is not a compression library museum, and so the options can be limited to what is likely to be useful in practice: - GZIP is tried and tested, and is still one of the fastest at decompression time, although the compression ratio is not very high; moreover, Fedora is already shipping EFI zboot kernels for arm64 that use GZIP, and QEMU implements direct support for it when booting a kernel without firmware loaded; - ZSTD has a very high compression ratio (although not the highest), and is almost as fast as GZIP at decompression time. Reducing the number of options makes it less of a hassle for other consumers of the EFI zboot format (such as QEMU today, and kexec in the future) to support it transparently without having to carry 7 different decompression libraries.

firmware: microchip: fix UL_IAP lock check in mpfs_auto_update_state()

2024-12-05T15:08:51Z

To verify that Auto Update is possible, the mpfs_auto_update_state() function performs a "Query Security Service Request" to the system controller. Previously, the check was performed on the first element of the response message, which was accessed using a 32-bit pointer. This caused the bitwise operation to reference incorrect data, as the response should be inspected at the byte level. Fixed this by casting the response to a u8 * pointer, ensuring the check correctly inspects the appropriate byte of the response message. Additionally, rename "UL_Auto Update" to "UL_IAP" to match the PolarFire Family System Services User Guide. Signed-off-by: Valentina Fernandez Signed-off-by: Conor Dooley

firmware: arm_ffa: Fix the race around setting ffa_dev->properties

2024-12-04T09:59:54Z

Currently, ffa_dev->properties is set after the ffa_device_register() call return in ffa_setup_partitions(). This could potentially result in a race where the partition's properties is accessed while probing struct ffa_device before it is set. Update the ffa_device_register() to receive ffa_partition_info so all the data from the partition information received from the firmware can be updated into the struct ffa_device before the calling device_register() in ffa_device_register().
