2024-12-16nios2: Use str_yes_no() helper in show_cpuinfo()Thorsten Blum1-5/+5
Remove hard-coded strings by using the str_yes_no() helper function. Signed-off-by: Thorsten Blum <[email protected]> Signed-off-by: Dinh Nguyen <[email protected]>
2023-06-13nios2: Replace all non-returning strlcpy with strscpyAzeem Shaikh1-1/+1
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

2018-09-28nios2: get cpu node with of_get_cpu_nodeRob Herring1-1/+3
"device_type" use is deprecated for FDT though it has continued to be used for nodes like cpu nodes. Use of_get_cpu_node() instead which works using node names by default. This will allow the eventually removal of cpu device_type properties. Also, fix a leaked reference by adding a missing of_node_put.

2017-05-08nios2: Add CDX supportMarek Vasut1-2/+8
Add support for the CDX Code Density Extensions present in Nios II R2 . This introduces new 16bit instruction set to improve code density while retaining support for the 32bit Nios II R2 instructions. Signed-off-by: Marek Vasut <[email protected]> Cc: Ley Foon Tan <[email protected]>
2017-05-08nios2: Add BMX supportMarek Vasut1-2/+8
Add support for the BMX Bit Manipulation Extensions present in Nios II R2 . This introduces three new instructions, EXTRACT, INSERT and MERGE. Signed-off-by: Marek Vasut <[email protected]> Cc: Ley Foon Tan <[email protected]>
2017-05-08nios2: Add NIOS2_ARCH_REVISION to select between R1 and R2Marek Vasut1-0/+2
Allow user to select between Nios2 R1 and R2. Since R1 and R2 are not binary compatible, we cannot have a single kernel binary and there is no point in having DT property for discerning these two. Signed-off-by: Marek Vasut <[email protected]> Cc: Ley Foon Tan <[email protected]>
2016-10-06nios2: use of_property_read_boolLey Foon Tan1-10/+5
Use of_property_read_bool instead of open-coding it as fpcu_has. Convert the members of struct cpuinfo from u32 to bool accordingly as they are only used as boolean anyhow. Signed-off-by: Tobias Klauser <[email protected]> Acked-by: Ley Foon Tan <[email protected]>
2015-04-15nios2: cpuinfo: remove use of seq_printf return valueJoe Perches1-39/+38
The seq_printf return value, because it's frequently misused, will eventually be converted to void.
