2009-09-16Blackfin: update ftrace for latest toolchainYi Li2-12/+13
The mcount support that was finally added to the Blackfin gcc port isn't exactly the same as what ftrace was developed against. Now that the final gcc version is in place, update the ftrace code to match. While updating this, fix the swapped arguments to the tracer (signature is (ip, parent_ip) while we were passing (parent_ip, ip)).

2009-09-16Blackfin: fix elf_fpregset_t definitionMike Frysinger1-1/+1
The elf_fpregset_t type relied on an empty struct in the asm/user.h, but the transition to asm-generic/user.h dropped that empty struct. Rather than restore this useless struct, define the only user (elf_fpregset_t) as an empty struct itself. This fixes building when ELF dump support is enabled.

2009-09-16Blackfin: unify cache init functionsMike Frysinger5-145/+45
The CPLB implementations (mpu/nompu) had exact copies of the cacheinit code. Even the i/d cache functions are largely the same. So unify them both in the common kernel cache code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Commit 71e308a239c updated ftrace_push_return_trace() prototype but didn't update the Blackfin ftrace code, so things broke. Since we don't support the new stuff yet, call it with stub values. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: increase default async timings for parallel flashesSonic Zhang4-7/+7
The default async timings are a little too fast for the parallel flash that is attached by default to the async banks. So slow things down a bit so accessing the hardware is stable. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: use raw_smp_processor_id() in exception codeYi Li3-8/+8
When preempt debugging is enabled, smp_processor_id() may utilize the "current" structure. This may not be safe to access under all exceptions due to it being in dynamically allocated memory. So in exception code, make sure we use raw_smp_processor_id() instead to get at the real value directly. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: Fix link errors with binutils 2.19 and GCC 4.3Ingo Molnar1-2/+2
Not sure whether this has been reported/fixed before. Today I built a Blackfin tool-chain from scratch for -tip testing, and it triggers: arch/blackfin/kernel/vmlinux.lds:1238: undefined section `.data_a_l1' referenced in expression and: arch/blackfin/kernel/vmlinux.lds:1238: undefined section `.text_data_l1' referenced in expression Now i dont have any way to test this linker script, but it now at least builds fine after fixing what appears to be typos in those assert statements.

2009-09-16Blackfin: optimize fixed code handling for the most common caseMike Frysinger2-8/+8
The majority of the time we are returning to user space, it is not in the fixed atomic code region. So rather than branch to a function where we check the PC and return, do the check inline and branch only when needed. Also, tweak some of the fixed code handling based on assumptions we are aware of but cannot be expressed in C. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: delete '-spi' suffix in ad1836/ad1938 driver nameBarry Song13-14/+14
The ASoC drivers have dropped the redundant "-spi" suffix in the driver name, so update the board resources accordingly. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: punt dead cache locking codeMike Frysinger5-284/+0
No one uses these functions, and some are duplicate of existing C code. So just punt the whole thing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: drop board resources for dead devices (pbx/ad9960)Mike Frysinger11-304/+0

2009-09-16Blackfin: do not trace the exception handlerYi Li1-1/+1

2009-09-16Blackfin: cleanup sync handling when enabling/disabling cplbsYi Li8-166/+84
The handling of updating the [DI]MEM_CONTROL MMRs does not follow proper sync procedures as laid out in the Blackfin programming manual. So rather than audit/fix every call location, create helper functions that do the right things in order to safely update these MMRs. Then convert all call sites to use these new helper functions. While we're fixing the code, drop the workaround for anomaly 05000125 as that anomaly applies to old versions of silicon that we do not support.

2009-09-16Blackfin: bf548-ezkit: fix incorrect LCD size parametersStefan Pledl1-2/+2
I think we have to use the physical dimensions [mm] of the display for .width and .heigth in struct bfin_bf54xfb_mach_info bf54x_lq043_data which are copied to fbinfo->var.height/.width in bf54x-lq043fb.c. linux/fb.h describes this values as 'height/weight of picture in mm' Otherwise QT calcs the wrong dpi value and the displayed fonts are very small.

2009-09-16Blackfin: bf537-stamp: drop ATA interrupt probe workaroundBarry Song1-5/+0
The interrupt probe workaround doesn't work without hacks to common code, and the add-on card only needs a simple resistor to fix the problem, so drop the board-specific hack. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: improve double fault debug handlingGraf Yang6-21/+37
Since the hardware only provides reporting for the last exception handled, and the values are valid only when executing the exception handler, we need to save the context for reporting at a later point. While we do this for one exception, it doesn't work properly when handling a second one as the original exception is clobbered by the double fault. So when double fault debugging is enabled, create a dedicated shadow of these values and save/restore out of there. Now the crash report properly displays the first exception as well as the second one. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: fix MPU handling of invalid memory accessesGraf Yang2-4/+4
The protect_page() function was incorrectly setting up the hardware tables based on possible access capabilities rather than the actual requested values. This means we would grant more access to mmap-ed pages than we should have. Once we fix this, we need to tweak the signal generated by such accesses to aline ourselves with other ports. This allows the LTP mmap0{5,6,7} cases to run properly. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: do not try displaying the end of the stackSonic Zhang1-1/+1
The end of the stack may not be valid (and that could be OK), so do not attempt to parse it. If we do, we might use a bad pointer in kernel space which makes things panic(). Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
