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

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
