arm: mvebu: Add gdsys ControlCenter-Compact board The gdsys ControlCenter Digital board is based on a Marvell Armada 38x SOC. It boots from SPI-Flash but can be configured to boot from SD-card for factory programming and testing. On board peripherals include: - 2 x GbE - Xilinx Kintex-7 FPGA connected via PCIe - mSATA - USB3 host - Atmel TPM Signed-off-by: Dirk Eibach <dirk.eibach@gdsys.cc> Signed-off-by: Mario Six <mario.six@gdsys.cc> Signed-off-by: Stefan Roese <sr@denx.de> 2017-02-22 15:07:23 +00:00			`#`

arm: mvebu: Remove dummy BIN header arguments for SPL binary U-Boot SPL binary does not read BIN header arguments, so passing some dummy values 0000005b and 00000068 has no effect for U-Boot SPL code. Probably these two values comes from old Marvell DDR training code which was separated from U-Boot and used it for some configuration. Seems that two 32-bit values were specified here to ensure SPL code alignment to 128-bit boundary as it is required e.g. for A370 or AXP processors. Main kwbimage header is 64-byte long which is aligned to 128-bit boundary. Optional kwbheader is 32-bit long, number of BIN header arguments is stored in 32-bit number. So for alignment to 128-bit boundary is needed 64-bit padding which exactly these two 32-bit dummy arguments provided. Now when mkimage correctly aligns start of executable code in BIN header to 128-bit boundary, there is no requirement to put dummy argument values into kwbimage. So remove them.
