m68k/mac: Fix unexpected interrupt with CONFIG_EARLY_PRINTK

2013-05-31T08:43:18Z

The present code does not wait for the SCC to finish resetting itself before trying to initialise the device. The result is that the SCC interrupt sources become enabled (if they weren't already). This leads to an early boot crash (unexpected interrupt) given CONFIG_EARLY_PRINTK. Fix this by adding a delay. A successful reset disables the interrupt sources. Also, after the reset for channel A setup, the SCC then gets a second reset for channel B setup which leaves channel A uninitialised again. Fix this by performing the reset only once.

m68k/mac: early console

2011-12-10T18:52:45Z

Revive the old mac_serial_print() routine as mac_early_print(). mac_serial_print() did not function because it did not use the right offsets for its stack arguments. Fix this and make compilation conditional on CONFIG_EARLY_PRINTK instead of the obscure MAC_SERIAL_DEBUG macro. Give mac_early_print() a new string length parameter to fit the early console API. Send output to the framebuffer as well as serial ports. Change the line rate to 38400 baud to match the default for the real (pmac_zilog) serial console.

m68k: convert to use __HEAD and HEAD_TEXT macros.

2009-04-26T16:20:38Z

This has the consequence of changing the section name use for head code from ".text.head" to ".head.text". Since this commit changes all users in the architecture, this change should be harmless.

m68k: Correct jump if not running on HP300

2008-05-18T20:28:49Z

When running a HP300-enabled kernel on non-HP300 hardware, a test in the early startup code jumps to the wrong label, causing a double bus fault. Signed-off-by: Geert Uytterhoeven Signed-off-by: Linus Torvalds

m68k: use .text.head

2007-07-20T15:24:49Z

i.e. tell modpost that entry point code (that has to be outside of .init.text for external reasons) is OK to refer to .init.* Signed-off-by: Al Viro Signed-off-by: Linus Torvalds
