Raw Normal View History Unescape

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user get_irqnr_preamble allows machines to take some action before entering the get_irqnr_and_base loop. On iop we enable cp6 access. arch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace. Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.

ARM: OMAP3: Add minimal omap3430 support Add minimal omap3430 support based on earlier patches from Syed Mohammed Khasim. Also merge in omap34xx SRAM support from Karthik Dasu and use consistent naming for sram init functions. Also do following changes that make 34xx support usable: - Remove unused sram.c functions for 34xx - Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally in entry-macro.S - Update mach-omap2/io.c to support 2420, 2430, and 34xx - Also merge in 34xx GPMC changes to add fields wr_access and wr_data_mux_bus from Adrian Hunter - Remove memory initialization call omap2_init_memory() until until more generic memory initialization patches are posted. It's OK to rely on bootloader initialization until then.

ARM: OMAP: Fix get_irqnr_and_base to clear spurious interrupt bits On omap24xx, INTCPS_SIR_IRQ_OFFSET bits [6:0] contains the current active interrupt number. However, on 34xx INTCPS_SIR_IRQ_OFFSET bits [31:7] also contains the SPURIOUSIRQFLAG, which gets set if the interrupt sorting information is invalid. If the SPURIOUSIRQFLAG bits are not ignored, the interrupt code will occasionally produce a bunch of confusing errors: irq -33, desc: c02ddcc8, depth: 0, count: 0, unhandled: 0 ->handle_irq(): c006f23c, handle_bad_irq+0x0/0x22c ->chip(): 00000000, 0x0 ->action(): 00000000 Fix this by masking out only the ACTIVEIRQ bits.

ARM: OMAP2: Change 24xx to use new register access This patch changes 24xx to use new register access, except for clock framework. Clock framework register access will get updates in the next patch. Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses. Also note that sleep.S removes some unused registers addresses. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
