 | 
			
		||||
 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.

 |

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.
