Subject: [PATCH 49/93] DNCPE-296 PFE reset woraround fix
|
||
|
|
||
|
- Linux driver depends on U-boot TMU initialization,
|
||
|
but U-boot tmu initialization is not as expected by Linux driver.
|
||
|
- Align U-boot TMU initialization with Linux driver
|
||
|
- LLM base address in DDR changed to match with Linux driver expectation.
|
||
|
- Remove unwanted pfe_mod.h
|
||
|
- Start PFE/network at bootup time.
