Subject: Add optimized Makefile support for SoCFPGA handoff
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=87cb318344250ac7d598284c0a1928df6bcd1f4e;p=pandora-u-boot.git

Add optimized Makefile support for SoCFPGA handoff

- Introduce socfpga_g5_handoff_prepare target in U-Boot
  arch/arm/mach-socfpga/config.mk
- Users can convert the handoff via make prepare.
- Detects Altera/Intel SoCFPGA boards from .config
- Combines vendor/board extraction into a single shell call
- Checks for hps_isw_handoff folder and .hiof files
- Uses ls -d instead of find for faster folder detection
- Runs BSP generator script only if files exist
- Non-blocking: continues if handoff folder or files are missing
- HANDOFF_PATH user define allows overriding auto-detected folder
- Minimizes subshells and other slow constructs for faster CI
