Subject: [PATCH 2/8] board: sifive: spl: Initialized the PWM setting in the
|
||||||
|
SPL stage
|
||||||
|
|
||||||
|
LEDs and multiple fans can be controlled by SPL. This patch ensures
|
||||||
|
that all fans have been enabled in the SPL stage. In addition, the
|
||||||
|
LED's color will be set to yellow.

Set LED's color to purple in the U-boot stage. Because there are still
|
||||||
|
some functions to be executed before board_early_init_f(), it means
|
||||||
|
the LED's is not changed to purple instantly when entering the U-boot

stage.

Subject: [PATCH 1/2] board: sifive: Set LED's color to blue before jumping to
|
||||||
|
Linux
|
||||||
|
|
||||||
|
The LED's color wil be changed from purple to blue before executing
|
||||||
|
the sysboot command. Because the sysboot command includes the image loading
|
||||||
|
from the boot partition, It means the LED's color is blue when executing
|
||||||
|
"Retrieving file: /Image.gz".

Subject: [PATCH] riscv: dts: Add few PMU events
|
||||||
|
|
||||||
|
fu740 has 2 HPM counters and many HPM events defined in the fu740 manual[1].
|
||||||
|
This patch adds some of these events and their mapping as per the
|
||||||
|
OpenSBI PMU DT binding for now.

riscv: Fix build against binutils 2.38
|
||||||
|
|
||||||
|
The following description is copied from the equivalent patch for the
|
||||||
|
Linux Kernel proposed by Aurelien Jarno:
|
||||||
|
|
||||||
|
>From version 2.38, binutils default to ISA spec version 20191213. This
|
||||||
|
means that the csr read/write (csrr*/csrw*) instructions and fence.i
|
||||||
|
instruction has separated from the `I` extension, become two standalone
|
||||||
|
extensions: Zicsr and Zifencei. As the kernel uses those instruction,
|
||||||
|
this causes the following build failure:

Subject: mkimage: check environment for dtc binary location
|
||||||
|
|
||||||
|
Currently mkimage assumes the dtc binary is in the path and fails
|
||||||
|
otherwise. This patch makes it check the DTC environment variable first
|
||||||
|
for the dtc binary and then fall back to the default path. This makes
|
||||||
|
it possible to call the u-boot build with make DTC=... and build a fit
|
||||||
|
image with the dtc binary not being the the default path.
