platform: Remove the HiFive Unleashed expansion board DT.

2019-07-02T04:46:00Z

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 Since, OpenSBI will directly load the pre-built DTB from kernel now onwards, no need to keep the out-of-date DT in openSBI.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.

firmware: For no relocation skip two stage wait for secondary HARTs

2019-07-01T03:24:13Z

When relocation is not required (i.e. _load_start == _link_start), we can skip two stage wait for secondary HARTs. This means secondary HARTs can skip the _wait_relocate_copy_done() loop and directly jump to the _wait_for_boot_hart() loop when no relocation not required. Signed-off-by: Anup Patel

scripts: Add Ariane FPGA to platform list in binary archive script

2019-06-30T06:37:56Z

This patch adds Ariane FPGA to RV64 platform list in the binary archive script. Signed-off-by: Anup Patel

docs: Update the fu540 platform guide for new DT.

2019-06-30T06:26:57Z

With 5.2-rc6 release, Linux kernel hosts the DT for Unleashed board which is incompatible with the default DT from FSBL. Update the document to use the DT from kernel. Signed-off-by: Atish Patra Acked-by: Anup Patel

include: Add firmware context to sbi_platform

2019-06-29T15:29:45Z

Add firmware context field struct sbi_platform to carry firmware specific information. Signed-off-by: Abner Chang Acked-by: Anup Patel

include: Add version info to struct sbi_platform

2019-06-29T13:56:26Z

Add version control of sbi_platform structure - Add opensbi_version, this gives information of opensbi revision on which the sbi_platform table was created. - Add platform_version field in sbi_platform structure for platform level version control. Signed-off-by: Abner Chang Acked-by: Anup Patel

include: Move callbacks in sbi_platform to separate struct

2019-06-29T12:50:00Z

Move platform opensbi functions to sbi_platform_operations structure. Both sbi_platform and sbi_platform_operations structures are maintained by platform vendors. Signed-off-by: Abner Chang Acked-by: Anup Patel

Add support for Ariane FPGA SoC

2019-06-29T11:34:06Z

This patch adds support for Ariane platform. We needed to enable PLIC interrupts early(like on BBL) due to some issue of the design. Otherwise, Linux would not get any external interrupts. Signed-off-by: Panagiotis Peristerakis
