I always encouter this simple error message compiling 2.6 for ML403 UART 16550

[Mohammad Sadegh Sadri]

Well

Don't know if any change should occure in the source files but when I compi=
le any version of 2.6 kernel for ml403/405 with UART 16550 support , I enco=
unter this error message :

arch/ppc/syslib/virtex_devices.c: In function 'virtex_early_serial_init':
arch/ppc/syslib/virtex_devices.c:309: warning: implicit declaration of func=
tion 'gen550_init'
  CC      arch/ppc/syslib/ppc4xx_setup.o
  CC      arch/ppc/syslib/gen550_dbg.o
arch/ppc/syslib/gen550_dbg.c:34: error: 'RS_TABLE_SIZE' undeclared here (no=
t in a function)
arch/ppc/syslib/gen550_dbg.c:36: error: empty scalar initializer
arch/ppc/syslib/gen550_dbg.c:36: error: (near initialization for 'rs_table'=
)
make[1]: *** [arch/ppc/syslib/gen550_dbg.o] Error 1
make: *** [arch/ppc/syslib] Error 2

And for the solution I simply add the following line to the header of gen55=
0_dbg.c :

#include=20

Is there any thing I have missed? or this include line should be added to t=
he source codes?

thanks.

Hmm, yes.  That looks busted.  Try the attached patch and see if it
works for you.

Oops; that patch won't work.  Try this one instead.

    What really needs to be done is to create some kind of mini-driver
architecture for the boot and debug serial drivers.
    There are only something like 4 or 5 simple functions, and in many
cases only putchar() needs implimented.
   
    The whole boot/debug early serial stuff is highly and unescesarily
8250 specific. While there are several alternatives,
    these typically involve numerous #ifdef's and then end up being
board specific.
   
    Being able to output data, before linux has loaded, or before the
standard serial drivers have initialized is probably not important for
    working systems, but is incredibly useful when trying to bring up a
new board - particularly if you are trying to do so with
    silly scopes, logic analyzers, and other electronic gizmo's
