Subject: [PATCH 0/8] MIPS: Unify low-level debugging functionalities
Date: Sun, 29 Oct 2023 02:53:01 +0000 [thread overview]
Message-ID: <20231029-mips_debug_ll-v1-0-d7a491e8c278@flygoat.com> (raw)
Hi all,
This is a attempt to bring all low-level debugging print functions
together and provide a arm-like low-level debugging interface and
a further function to debug early exceptions.
The plan is to elimiate platform specific early_printk and
cps-vec-ns16550 by debug_ll and earlycon.
cps-vec-ns16550 is leave unchanged for now due to pending patch[1].
Hope you'll find them handy :-)
Happy hacking!
Thanks
Jiaxun
