platform: Remove the ipi_sync method from all platforms.

2019-08-16T03:12:58Z

OpenSBI manages outstanding TLB flush requests by queueing them in a fifo synchronously. An ipi sync which uses an atomic operation on MMIO address is no longer required. Remove the ipi sync method from platform header and all usage. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

platform: sifive: fu540: Expand FDT size before any patching

2019-08-09T07:00:06Z

We should expand the FDT size before any patching, otherwise it's possible the "status" fix up might fail due to insufficient space. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

platform: sifive/fu540: Move FDT further up

2019-07-24T03:54:28Z

This patch changes FW_xyz_FDT_ADDR to RAM_START+128MB (i.e. 0x88000000) so that next stage bootloader (i.e. U-Boot) has enough space to unpack bigger kernel images.

platform: sifive: fu540: Use standard value string for cpu node status

2019-07-22T05:44:05Z

Per device tree spec, the standard value string for the "status" property of a cpu node is either "okay" or "disabled". "masked" was once used but it is unfortunately a spec violation. Signed-off-by: Bin Meng Acked-by: Anup Patel

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 Since, OpenSBI will directly load the pre-built DTB from kernel now onwards, no need to keep the out-of-date DT in openSBI.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

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

platform: Enable all drivers by default.

2019-06-19T04:19:05Z

The drivers and libfdt are built as libsbiutils.a instead of libplatsbi.a. libsbiutils.a are not built per platform specific. Thus, enable all drivers by default. Signed-off-by: Atish Patra Acked-by: Anup Patel

platform: Move platform common to lib/utils.

2019-06-19T04:18:56Z

Currently, platform/common contains platform/non-platform specific common minimal drivers and libraries. This is helpful is all platforms are built within opensbi framework. Move them to lib/utils so that any external platform code also can reuse the minimalistic drivers or other common libraries. This patch doesn't introduce any functional changes.

2019-05-10T06:56:22Z
