Replace TARGET namespace and cleanup properly

2026-02-14T17:06:46+00:00

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.

drivers: firmware: update xilinx_pm_request to support max payload

2025-10-09T07:07:03+00:00

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.

fpga: lattice: Remove unused support

2025-08-25T14:20:48+00:00

There is no single platform which is using this driver that's why remove it
completely. Some issues regarding this code are also reported by Coverity
(CID 583143, 583144, 583145, 583146).

arm: socfpga: Remove unnecessary for loop

2025-07-30T09:45:28+00:00

The for loop in fpgamgr_program_poll_cd will always terminate after a
single pass and so is not necessary. Remove it and all related code and
leave only the code that is effective.

This issue was found by Smatch.

2025-07-24T06:54:15+00:00

As reported by clang 20.1, fix multiple of the following:
 drivers/fpga/ivm_core.c:593:23: error: a function declaration without
 a prototype is deprecated in all versions of C
 [-Werror,-Wstrict-prototypes]

drivers: fpga: cleanup printf usage

2025-07-24T06:54:15+00:00

Remove `fpga_no_sup` to get rid of Werror=unused-function when all
FPGA configurations are enabled.

Swap all printf calls to log_* as this is now preferred and includes
the calling __func__.

drivers: fpga: correct compiler errors and warnings

2025-07-24T06:54:15+00:00

Errors reported by GCC 14.2 when enabling FPGA commands and
drivers. Also many style fixes as reported by checkpatch.pl on the
diffs. Most changes in stratixII.c which has been reorganized as well
to avoid the top function prototypes.

No functional changes.
