[POWERPC] QE: fix Kconfig 'select' warning with UCC_FAST

2007-05-23T12:23:55+00:00

The UCC_GETH Kconfig option in drivers/net/Kconfig had a line to select the
UCC_FAST option is arch/powerpc/sysdev/qe_lib/Kconfig, which is only used
on PowerPC builds.  On other architectures, this would generated a warning.
The fix is to have UCC_FAST depend on UCC_GETH.

[POWERPC] Change rheap functions to use ulongs instead of pointers

2007-05-10T04:01:43+00:00

The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer.  A ulong is a better representation of the value returned by
the allocation functions.

This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer.  In case of an error, the value returned is
a negative error code that has been cast to an unsigned long.  The caller can
use the IS_ERR_VALUE() macro to check for this.

All code which calls the rheap functions is updated accordingly.  Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().

Also added error checking to rh_attach_region().

[POWERPC] QE: fix invalid pointer usage in ucc_slow_init()

2007-03-26T22:06:22+00:00

In two places, ucc_slow_init() passes a physical address instead of the
virtual address to functions that were expecting the latter, causing a kernel
panic.  us_info->regs contains the physical address of the UCC register set.
The registers are ioremap'd to kernel space, and the virtual pointers are
stored in us_regs.  The code was using us_info->regs when it should have been
using us_regs.

[POWERPC] QE: automatically select QE options

2007-03-26T22:05:22+00:00

Change the Kconfig files so that the Freescale QE options are automatically
selected if a QE device is selected.  Previously, you'd need to manually
select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet.
Now, the QE Gigabit Ethernet option is always available if the device has a
QE, and UCC_FAST is automatically enabled.  A side-effect is that the
"QE Options" menu no longer exists.
