hello,
Trying to boot linux-2.6.14-rc3 on TQM8260 I found,
that following line is missing in file arch/ppc/syslib/m8260_setup.c:
-----------------------------------------------------------------------
--- m8260_setup.c.org 2005-10-07 16:42:41.420238000 +0200
+++ m8260_setup.c 2005-10-07 16:41:58.811408400 +0200
@@ -249,6 +249,8 @@
strcpy(cmd_line, (char *)(r6+KERNELBASE));
}
+ identify_ppc_sys_by_id(mfspr(SPRN_SVR));
+
ppc_md.setup_arch = m8260_setup_arch;
ppc_md.show_cpuinfo = m8260_show_cpuinfo;
ppc_md.init_IRQ = m8260_init_IRQ;
---------------------------------------------------------------------
if not set, we get problem here:
static int __init ppc_sys_init(void)
{
unsigned int i, dev_id, ret = 0;
BUG_ON(cur_ppc_sys_spec == NULL); <--------------------------
Moreover the default configuration found in
arch/ppc/configs/TQM8260_defconfig
doesn't work or I do something wrong.
for example configuration of serial port:
#
# Serial drivers
#
CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
# CONFIG_SERIAL_8250_EXTENDED is not set
#
# Non-8250 serial port support
#
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_UNIX98_PTYS=y
CONFIG_UNIX98_PTY_COUNT=32
inspite of this I use following(SMC1):
#
# Serial drivers
#
# CONFIG_SERIAL_8250 is not set
#
# Non-8250 serial port support
#
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_SERIAL_CPM=y
CONFIG_SERIAL_CPM_CONSOLE=y
# CONFIG_SERIAL_CPM_SCC1 is not set
# CONFIG_SERIAL_CPM_SCC2 is not set
# CONFIG_SERIAL_CPM_SCC3 is not set
# CONFIG_SERIAL_CPM_SCC4 is not set
CONFIG_SERIAL_CPM_SMC1=y
# CONFIG_SERIAL_CPM_SMC2 is not set
CONFIG_UNIX98_PTYS=y
CONFIG_LEGACY_PTYS=y
CONFIG_LEGACY_PTY_COUNT=256
best regards
Pawel

This is not quite right. For these types of boards (at least, most of),
the soc id is stored in the immr register. But yes, that's definitely a
problem, I'll take a look at this asap.
