memory: atmel-sdramc: remove the driver

2023-06-02T08:39:24+00:00

Driver does only clock request + enable for DDR clocks. DDR clocks are enabled by bootloader and need to stay that way in Linux. To avoid having these clocks disabled by clock subsystem in case there are no Linux consumers for them the clocks were marked as critical in clock drivers (in commit 68b3b6f1773d ("clk: at91: mark ddr clocks as critical")). With this, there is no need to have a separate driver that only does clock request + enable.

ARM: 9263/1: use .arch directives instead of assembler command line flags

2022-11-08T18:36:17+00:00

Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler directives instead of assembler arguments"). GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.

memory: dfl-emif: add the DFL EMIF private feature driver

2021-01-07T14:21:27+00:00

This driver is for the EMIF private feature implemented under FPGA Device Feature List (DFL) framework. It is used to expose memory interface status information as well as memory clearing control. The purpose of memory clearing block is to zero out all private memory when FPGA is to be reprogrammed. This gives users a reliable method to prevent potential data leakage.

memory: Add Baikal-T1 L2-cache Control Block driver

2020-05-28T12:17:41+00:00

Baikal-T1 SoC provides a way to tune the MIPS P5600 CM2 L2-cache performance up. It can be done by changing the L2-RAM Data/Tag/WS latencies in a dedicated register exposed by the system controller. The driver added by this commit provides a dts properties-based and sysfs-based interface for it. The device DT node is supposed to be a child of Baikal-T1 System Controller node.
