platform: Drop qemu/sifive_u support

2020-02-07T05:31:01Z

With QEMU v4.2 RISC-V changes to improve the emulation fidelity of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10 / Linux kernel v5.3 images built for the SiFive HiFive Unleashed board can be used out of the box without any special hack. Hence there is no need for us to continue supporting such a special target in OpenSBI. Going forward, sifive/fu540 platform can be used on both real hardware and QEMU 'sifive_u' machine.

Makefile: Add support for device tree compilation

2019-01-21T04:28:33Z

Add rules to compile dts files into dtb files using the device tree compiler (dtc). A platform can specify the DTS file to compile using the platform-dtb-y variable. The flattened device tree binary file to be used for building the final polatform firmware can be specified using the new FW_PAYLOAD_FDT firmware configuration option to point to the automatically compiled FDT file. Using the existing FW_PAYLOAD_FDT_PATH configuration option is still possible and will take precedence over the FW_PAYLOAD_FDT definition. Signed-off-by: Damien Le Moal

build: Introduce FW_PAYLOAD_ALIGN

2019-01-21T04:28:33Z

The firmware payload offset defined by FW_PAYLOAD_OFFSET must specify a value large enough so the the payload does not overlap with the base firmware data, bss and text. For platforms without any strong requirement on the payload address, introduce the FW_PAYLOAD_ALIGN build parameter to automatically place the payload right after the base firmware at an address aligned with the defined value. Either FW_PAYLOAD_OFFSET or FW_PAYLOAD_ALIGN should be defined by a platform configuration. If both FW_PAYLOAD_OFFSET and FW_PAYLOAD_ALIGN are defined by a platform, FW_PAYLOAD_OFFSET has precedence and is used for building the final firmawre image. Using FW_PAYLOAD_ALIGN=4096 with the Kendryte platform rather than the abitrary FW_PAYLOAD_OFFSET=0x10000 value reduces the final firmware image size by about 20KB. Add a description of the FW_PAYLOAD_ALIGN configuration parameter in the fw_payload documentation file as well. And while at it, also fix various grammar and style issues in that file..
