* [ARM] pxa: cpufreq-pxa2xx: sdram_rows detection supportPhilipp Zabel2008-12-022-3/+27
| | | | | | | | | | This patch implements Eric Miao's idea to detect the correct value of sdram_rows by inspecting the MDCNFG register settings. It is only tested on two pxa27x devices with 64MB RAM (magician and hx4700) so far. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>
* [ARM] pxa: cpufreq-pxa2xx: allow frequency table selectionMarc Zyngier2008-12-021-13/+19
| | | | | | | | | | | | | | | | | | | | Following the removal of the "->policy" usage for PXA255 in patch 459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove policy->governor setting in drivers initialization), this patch introduces an option (called "pxa255_turbo_table") to select either the "run" or "turbo" frequency table. It also cures the runtime warning that was printed each time the frequency was changed. Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked with the run/turbo thing. Tested on an Arcom/Eurotech Viper. Signed-off-by: Marc Zyngier <maz@misterjones.org> Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Eric Miao <eric.miao@marvell.com>

* [ARM] pxa: add support for additional GPIOs on PXA26xEric Miao2008-12-025-16/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | Original patch from Marek Vasut, the problems with PXA26x are: 1. there are additional 4 GPIOs 86,87,88,89 have their direction bits inverted in GPDR2, as well as their alternate function bits being '1' for their GPIO functionality in GAFRx 2. there is no easy way to decide if the processor is a pxa26x or a pxa250/pxa255 at run-time, so the assumption here is the pxa26x will be treated as one of the pxa25x variants, and board code should have a better knowledge of the processor it is featured Introduce pxa26x_init_irq() for the second purpose, and treat the additional GPIOs > 85 on PXA25x specially. Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code a bit when PXA26x support isn't needed. Board config options have to select this to enable the support for PXA26x. __gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x isn't selected.

* Revert "[ARM] pxa: introduce cpu_is_pxa26x()"Eric Miao2008-12-022-9/+1
| | | | | | | | | | This reverts commit da1a3dc0ebb4f9209a1939eaa6b18901e0cd7bc0. The originally proposed way in the above commit is incorrect. And there is no easy way to distinguish between pxa25x and pxa26x at run-time. Signed-off-by: Eric Miao <eric.miao@marvell.com>
* [ARM] pxa: use 'pxa_last_gpio' instead of 'gpio_nr' in mfp-pxa2xx.cEric Miao2008-12-022-10/+6
| | | | | | | | | | | | The 'gpio_nr' can really be inferred by 'pxa_last_gpio', and since we already have that variable, remove the unnecessary 'gpio_nr' now. Also, fix the incorrect GPIO number passed in pxa27x_init_irq(). Note: pxa_last_gpio should be initialized earlier, and this is true since it's been assigned in machine_desc->init_irq().

They also provide a mode where all such accesses are forced to trap. The kernel was schizophrenic about use of this mode: * Base kernel code ran in permissive mode where the only traps generated were from those cases that the h/w could not handle. * Interrupt, syscall and trap code ran in strict mode where all unaligned accesses caused traps to the 0x5a00 unaligned reference vector. Use strict alignment checking throughout the kernel, but make sure that we continue to let user mode use more relaxed mode as the default. Signed-off-by: Tony Luck <tony.luck@intel.com>
