2009-07-23sh: convert processor device setup functions to arch_initcall()Magnus Damm
Convert the processor platform device setup functions from __initcall() and sometimes device_initcall() to arch_initcall(). This makes sure that the platform devices are registered a bit earlier so the devices are available when drivers register using initcall levels earlier than device_initcall(). A good example is platform devices needed by i2c-sh_mobile.c which registers a bit earlier using subsys_initcall().

2009-07-23usb: m66592-udc platform data on_chip supportMagnus Damm
Convert the m66592-udc driver to use the on_chip flag from platform data to enable on chip behaviour instead of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness. This makes the code cleaner and also allows us to support both external and internal m66592 with the same kernel. It also makes the Kconfig part more future proof since we with this patch can add support for new processors with on-chip m66592 without modifying the Kconfig. The patch adds a m66592 header file for platform data and ties in platform data to the existing m66592 devices.

2009-07-18vmlinux.lds.h: restructure BSS linker script macrosTim Abbott
The BSS section macros in vmlinux.lds.h currently place the .sbss input section outside the bounds of [__bss_start, __bss_end]. On all architectures except for microblaze that handle both .sbss and __bss_start/__bss_end, this is wrong: the .sbss input section is within the range [__bss_start, __bss_end]. Relatedly, the example code at the top of the file actually has __bss_start/__bss_end defined twice; I believe the right fix here is to define them in the BSS_SECTION macro but not in the BSS macro. Another problem with the current macros is that several architectures have an ALIGN(4) or some other small number just before __bss_stop in their linker scripts. The BSS_SECTION macro currently hardcodes this to 4; while it should really be an argument. It also ignores its sbss_align argument; fix that. mn10300 is the only user at present of any of the macros touched by this patch. It looks like mn10300 actually was incorrectly converted to use the new BSS() macro (the alignment of 4 prior to conversion was a __bss_stop alignment, but the argument to the BSS macro is a start alignment). So fix this as well. I'd like acks from Sam and David on this one. Also CCing Paul, since he has a patch from me which will need to be updated to use BSS_SECTION(0, PAGE_SIZE, 4) once this gets merged.

2009-07-16arch/blackfin: Add kmalloc NULL testsJulia Lawall
Check that the result of kmalloc is not NULL before passing it to other functions. In the first two cases, the new code returns -ENOMEM, which seems compatible with what is done for similar functions for other architectures. In the last two cases, the new code fails silently, ie just returns, because the function has void return type. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression *x; identifier f; constant char *C; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ... when != x == NULL when != x != NULL when != (x || ...)

2009-07-16Blackfin: drop per-cpu loops_per_jiffy trackingMichael Hennerich
On Blackfin SMP, a per-cpu loops_per_jiffy is pointless since both cores always run at the same CCLK. In addition, the current implementation has flaws since the main consumer for loops_per_jiffy (asm/delay.h) uses the global kernel loops_per_jiffy and not the per_cpu one. So punt all of the per-cpu handling and go back to the global shared one. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-16Blackfin: fix early_dma_memcpy() handling of busy channelsMike Frysinger
The early logic to locate a free DMA channel and then set it up was broken in a few ways that only manifested itself when we needed to set up more than 2 on chip SRAM regions (most board defaults setup 1 or 2). First, we checked the wrong status register (the destination gets updated, not the source) and second, we did the ssync before rather than after resetting a DMA config register.

2009-07-16Blackfin: fix miscompilation in lshrdi3Jie Zhang
The code used in the Blackfin lshrdi3 utilizes gcc constructs.

So rather than trying to maintain different gcc definitions ourselves, just use the ones available in gcclib.h.

2009-07-16Blackfin: fix silent crash when no uClinux MTD filesystem existsRobin Getz
Since we need to relocate the attached filesystem with the uClinux MTD map (to handle some anomalies), we need to know its real filesize. If we boot a kernel without a filesystem actually attached, we end up blindly reading and copying garbage (since there is no magic value to detect validity). Often times this results in an early crash and no output. So add a few basic sanity checks before operating on things to catch the majority of cases.

2009-07-16Blackfin: work around anomaly 05000281Robin Getz
Add missing anomaly workaround for anomaly 05000281 - we can't return to instructions which cause hardware errors otherwise we trigger the error again which means we go into an infinite loop of handling, returning, and retriggering. This work around confuses gdb when the error occurs as the PC will seemed to have moved, so a better long term fix will need to be figured out, but for now this is better than an infinite crash loop.
