The scratch space being a scarce resource so let us print it's size and usage at boot time. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

platform: Allow platforms to specify heap size

2023-06-05T10:15:33Z

We extend struct sbi_platform and struct sbi_scratch to allow platforms specify the heap size to the OpenSBI firmwares. The OpenSBI firmwares will use this information to determine the location of heap and provide heap base address in per-HART scratch space. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

include: sbi_scratch: Add helper macros to access data type

2023-06-05T10:12:50Z

Reading and writing a data type in scratch space is a very common use-case so let us add related helper macros in sbi_scratch.h. Signed-off-by: Anup Patel

firmware: Add RW section offset in scratch

2023-01-23T04:36:14Z

Add the RW section offset, provided by _fw_rw_offset symbol, to the scratch structure. This will be used to program separate pmp entry for RW section. Signed-off-by: Himanshu Chauhan Reviewed-by: Anup Patel

include: Use static asserts for SBI_SCRATCH_xxx_OFFSET defines

2022-03-27T04:14:54Z

Add static detection to prevent the modification of struct sbi_scratch from forgetting the modification of SBI_SCRATCH_xxx_OFFSET Signed-off-by: Xiang W Reviewed-by: Anup Patel

lib: fix pointer of type 'void *' used in arithmetic

2022-01-21T16:28:12Z

Using "void *" in arithmetic causes errors with strict compiler settings: "error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]" Avoid these by calculating on "char *" where 1-byte data size is assumed.

lib: sbi_scratch: remove owner from sbi_scratch_alloc_offset

2021-06-02T11:37:26Z

The parameter owner of function sbi_scratch_alloc_offset() is never used. The scratch memory is small. We should not use it for debug information in future. Hence eliminate the parameter. Signed-off-by: Heinrich Schuchardt Reviewed-by: Xiang W Reviewed-by: Anup Patel

include: headers: Replace ASSEMBLY with ASSEMBLER

2021-03-22T10:32:48Z

GCC has already a predefined macro __ASSEMBLER__ therefore, it can be used without the need to define a new flag with -D__ASSEMBLY__. This is useful when adding the library to projects having a build system such one can build without the need to make changes. THe build system does not use the Makefile in the sources tree.

include: sbi: No need to pack struct sbi_scratch

2021-01-15T05:10:31Z

All members in struct sbi_scrach are of machine word size so no need to pack this structure. This also allows GCC to generate more optimized instruction sequence when accessing members of struct sbi_scratch.
