Added 8xx SoC peripherials: fec for Ethernet and smc for UARTs. Ordinary routines to extract values from the device tree and insert respective platform devices Signed-off-by: NVitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Including support for non-coherent cache, some mm-related things + relevant field in Kconfig and Makefiles. Also included rheap.o compilation if 8xx is defined. Non-coherent mapping were refined and renamed according to Cristoph Hellwig. Orphaned functions were cleaned up. [Also removed arch/ppc/kernel/dma-mapping.c, because otherwise compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up with two copies of __dma_alloc_coherent etc. -- paulus.] Signed-off-by: NVitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

This is just a straight port of the same done in arch/ppc by Marcelo Tosatti. One used to be [PATCH] ppc32 8xx: update_mmu_cache() needs unconditional tlbie, commit eb07d964 In a nutshell, the board is nearly stuck without this, yet without any visible failure - being just very slow.

This makes cpm uart able to work using OF-passed parameters in case of CPM stuff (found on most mpc8xx reference and custom boards). The idea is to keep ppc stuff working yet making it able to be used for powerpc. Signed-off-by: NVitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

It's useful to have access to struct ipic handle that just got created in ipic_init(). For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense. With this we can mimic the old sense array concept that existed in arch/ppc. Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

Make the various 83xx *_init_IRQ() functions static Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

由 Kumar Gala 提交于
It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

- Drivers will not rely on the PCI config space value, as they've already been conditioned to rely on the irq field in "struct pci_dev". - The virq value may not be < 256 as it has been remapped. - The PCI config space should reflect the hardware configuration, which is not being changed. We are only creating a virtual irq mapping that exists in the kernel only. One would never expect the PCI hardware to generate the "virq" interrupt.

I often test new versions of glibc by doing: LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary> One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded at 0x8000000 (128MB) with the heap right after it. Since we normally link binaries at 0x10000000 (256MB) we only had about 128MB of space for the heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 08000000-0801e000 r-xp 00000000 00:01 33079 /lib/ld-2.5.so 0802d000-0802f000 rwxp 0001d000 00:01 33079 /lib/ld-2.5.so 0802f000-08050000 rwxp 0802f000 00:00 0 [heap] 0fe91000-0ffd9000 r-xp 00000000 00:01 33082 /lib/libc-2.5.so 0ffd9000-0ffe8000 ---p 00148000 00:01 33082 /lib/libc-2.5.so 0ffe8000-0ffea000 r--p 00147000 00:01 33082 /lib/libc-2.5.so 0ffea000-0ffed000 rwxp 00149000 00:01 33082 /lib/libc-2.5.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep ffb41000-ffb56000 rw-p ffb41000 00:00 0 [stack] One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
