From 622a42926e20d8ea4a21d3d90037b276f1f8f836 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Fri, 8 Jun 2001 13:32:08 +0000 Subject: 2000-06-08 Eric Valette * mpc8xx/console-generic/console-generic.c: The printk/printf did not work when loaded by EPPCBUG. They did work when loaded with the BDM debugger. I suspected EPPBUG made some nasty things like patching Communication processor microcode... Anyway, the attached patch: 1) Enables to have printk nearly immediately after boot, 2) Make printf work automagically (I do not know why except I make a different initialization for printk that should be overwritten by console init later ?) I let the default to be using EPPCBUG embedded firmware to boot and using this printk early enabler code (LOADED_BY_EPPCBUG and EARLY_CONSOLE) are on. --- c/src/lib/libcpu/powerpc/ChangeLog | 16 ++++++++++++++++ .../powerpc/mpc8xx/console-generic/console-generic.c | 1 + 2 files changed, 17 insertions(+) (limited to 'c/src/lib') diff --git a/c/src/lib/libcpu/powerpc/ChangeLog b/c/src/lib/libcpu/powerpc/ChangeLog index 055cda9c3b..8af12760a9 100644 --- a/c/src/lib/libcpu/powerpc/ChangeLog +++ b/c/src/lib/libcpu/powerpc/ChangeLog @@ -1,3 +1,19 @@ +2000-06-08 Eric Valette + + * mpc8xx/console-generic/console-generic.c: + The printk/printf did not work when loaded by EPPCBUG.
