payloads/test: Add support for SBI v0.2 ecalls

2021-08-20T04:18:45Z

It can be useful to make SBI v0.2 or newer ecalls from this payload for testing purposes. To support this, convert the macros to use the extension/function parameter convention. Signed-off-by: Samuel Holland Reviewed-by: Atish Patra

firmware: Use lla to access all global symbols

2021-03-19T09:27:45Z

When OpenSBI is compiled as fPIE mode, the assembler will translate "la" to GOT reference pattern. It will cause to cost an additional load instruction when obtaining the symbol address. However, if the symbol locates within the positive or negative 2GB region, we can use "lla" instead of "la" to avoid unneeded GOT references. This patch assumes that the OpenSBI image excluding the payload does not exceed 2GB. Based on this assumption, all "la" instructions are replaced by "lla" to avoid performance degradation when compiling as fPIE mode. Signed-off-by: Vincent Chen Reviewed-by: Anup Patel

firmware: Fix placement of .align directives

2020-01-10T04:00:27Z

Move the .align directives after switching the section. We want to align the start of the current section, not the end of the previous section. This also obsoletes the misguided workaround of disabling relaxation. Signed-off-by: Andreas Schwab Reviewed-by: Anup Patel

lib: Rename existing SBI implementation as 0.1.

2019-10-03T03:23:52Z

Current SBI implementation is now considered as version 0.1 and will be removed/replaced with newer extension/functions in future. Rename the existing implementations accordingly to be in sync with the specification. Signed-off-by: Atish Patra Reviewed-by: Anup Patel Reviewed-by: Zong Li

Test: Move test payload related code out of interface header

2019-10-03T03:21:39Z

Test payload uses an SBI call and uses the macros defined in interface header which is not the correct place to have these definitions. The interface header file should be used to keep SBI specification related macros. Keep all the test payload related code in test itself. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

firmware: Use CSR_ instead of for csr*

2019-02-14T04:01:18Z

Some older toolchains may not have all the csr's defined. Update all the csr functions to use the CSR_ #define values instead of the toolchain defined values. Signed-off-by: Atish Patra

all: Update copyright header in all files

2019-01-24T08:37:47Z

Define sbi_ecall_console_puts() using sbi_ecall_console_putchar() renamed as sbi_ecall_console_putc() and remove the hardcoded version of the same funtion in the test payload code. Signed-off-by: Damien Le Moal
