drivers: fpga: Use FPGA_INTEL_SDM_MAILBOX conditional instead of Agilex/Stratix10

2026-07-08T06:55:51Z

Replace the conditional compilation checks for CONFIG_ARCH_SOCFPGA_AGILEX and CONFIG_ARCH_SOCFPGA_STRATIX10 with CONFIG_FPGA_INTEL_SDM_MAILBOX.

treewide: prefer func over FUNCTION and __PRETTY_FUNCTION__

2026-06-10T20:49:46Z

__FUNCTION__ and __PRETTY_FUNCTION__ are gcc extensions that predate the C99 __func__ identifier. scripts/checkpatch.pl emits a warning for any new use of __FUNCTION__ and recommends __func__ instead. In C (unlike C++) __PRETTY_FUNCTION__ is identical to __func__ because C function names do not carry signature information, so the distinction has no behavioural effect here. The majority of the tree already uses __func__, but a handful of older files in arch/, board/, boot/, drivers/, examples/ and include/ still carry the gcc spellings (55 occurrences of __FUNCTION__ across 19 files plus one __PRETTY_FUNCTION__ in drivers/usb/musb-new/omap2430.c). Convert them all to the C99 form so the tree is consistent and new patches in these areas do not have to follow an outdated local style. Ten "Unnecessary ftrace-like logging - prefer using ftrace" warnings remain on the printf("%s\n", __func__) and dbg("%s\n", __func__) function-entry traces in drivers/net/rtl8169.c (behind DEBUG_RTL8169* preprocessor guards) and drivers/usb/host/ohci-hcd.c. checkpatch matches the literal "%s\n", __func__ shape regardless of the wrapper, so silencing those warnings would require changing the debug message text or removing the traces entirely.

fpga: versalpl: Fix unaligned buffer handling

2026-05-25T13:14:05Z

When fpga load is called with a misaligned buffer address, the versal_align_dma_buffer() function shifts the pointer forward to the next aligned boundary and uses memcpy() to copy the data. Since the destination is ahead of the source and the regions overlap, memcpy() produces undefined behavior; in practice U-Boot's generic memcpy() copies forward, repeating the first ARCH_DMA_MINALIGN-aligned chunk throughout the buffer. Replace memcpy() with memmove() which correctly handles overlapping regions by copying backwards when the destination is ahead of the source.

fpga: xilinx: Add option to skip bitstream ID check

2026-04-23T09:51:48Z

Add environment variable 'fpga_skip_idcheck' that when set to '1' or 'y' allows bypassing the device ID validation during bitstream loading. This is useful for loading bitstreams on devices whose ID codes are not yet recorded in the SOC driver. Usage: setenv fpga_skip_idcheck 1 fpga loadb 0 ${loadaddr} ${filesize} Signed-off-by: Michal Simek Link: https://lore.kernel.org/r/d0f11d0a8d48b284683f00d20dfbe323c11f2943.1776360720.git.michal.simek@amd.com

Replace TARGET namespace and cleanup properly

TARGET namespace is for machines / boards / what-have-you that building U-Boot for. Simply replace from TARGET to ARCH make things more clear and proper for ALL SoCFPGA. Signed-off-by: Brian Sune Reviewed-by: Tien Fong Chee # Conflicts: # drivers/ddr/altera/Makefile

drivers: firmware: update xilinx_pm_request to support max payload

2025-10-09T07:07:03Z

Currently xilinx_pm_request API supports four u32 payloads. However the legacy SMC format supports five u32 request payloads and extended SMC format supports six u32 request payloads. Add support for the same in xilinx_pm_request API. Also add two dummy arguments to all the callers of xilinx_pm_request. The TF-A always fills seven u32 return payload so add support for the same in xilinx_pm_request API.
