2020-10-18firmware: Remove FW_PAYLOAD_FDT_PATH compile-time optionAnup Patel
The FW_PAYLOAD_FDT_PATH compile-time option is replaced by FW_FDT_PATH compile-time option which is more flexible and common across all OpenSBI firmwares. This patch removes FW_PAYLOAD_FDT_PATH and updates related documentation to use FW_FDT_PATH. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>

2020-06-08docs: Remove redundant documentation about combined payload use caseAtish Patra
U-Boot now supports loading Linux kernel image via network and storage media. Thus, we don't need to use a combined payload containing both U-Boot & Linux kernel image to boot Linux from U-Boot prompt. Remove the old documentation.

2020-03-19platform: sifive/fu540: Remove FU540_ENABLED_HART_MASK optionAnup Patel
The FU540_ENABLED_HART_MASK compile time option was added for initial bring-up on SiFive Unleashed. This option is redundant now because disabled_hart_mask is already removed. Based on this rationale, we remove FU540_ENABLED_HART_MASK compile time option.

2020-01-10docs: platform: Update SiFive FU540 doc as-per U-Boot v2020.01Anup Patel
With U-Boot v2020.01, the SiFive FU540 DTB required by U-Boot is embedded in U-Boot binary itself so we don't need to do anything special for U-Boot v2020.01 as payload to OpenSBI firmware. This patch updates SiFive FU540 documenation assuming we use latest U-Boot v2020.01 release. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-09-25docs: platform: Update descriptions for qemu/sifive_u supportBin Meng
With QEMU v4.2 release that has improved the emulation fidelity of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10-rc1 / Linux kernel v5.3-rc2 images built for the SiFive HiFive Unleashed board can be used out of the box without any special hack. Update our documents to mention 'qemu/sifive_u' platform should only be used with QEMU v4.1 or before, and it will be dropped sometime in the future release. Going forward, 'sifive/fu540' platform can be used on both real hardware and QEMU v4.2+ 'sifive_u' machine. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>

2019-07-02platform: Remove the HiFive Unleashed expansion board DT.Atish Patra
The Linux kernel will maintain the device tree (DT) for HiFive Unleashed from release v5.2-rc6. This DT is incompatible with previous DT present for Microsemi expansion board in OpenSBI. Since, OpenSBI will directly load the pre-built DTB from kernel now onwards, no need to keep the out-of-date DT in openSBI. Remove this DT and it's related documentation.
