Don't look at all the VPHN counts, only distance_ref_points_depth worth.

However, they seem to use r5 as an index into the CPU table entry, which might have been right a long time ago but no longer is. r4 is the right register to use. This probably caused some off behaviours on some PowerMac variants using 750cx or 7455 processor revisions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: stable@kernel.org
| * | | | powerpc: Pass the right cpu_spec to ->setup_cpu() on 64-bitBenjamin Herrenschmidt2011-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When calling setup_cpu() on 64-bit, we pass a pointer to the cputable entry we have found. This used to be fine when cur_cpu_spec was a pointer to that entry, but nowadays, we copy the entry into a separate variable, and we do so before we call the setup_cpu() callback. That means that any attempt by that callback at patching the CPU table entry (to adjust CPU features for example) will patch the wrong table.

The Devkit8000 uses twl4030_ledA configured as output gpio only for the lcd enable line. twl4030_gpio.1 is used through the generic gpio functions while ledA is used via low level twl4030 calls. This patch removes the low level calls and use the generic gpio functions for initialization and use of ledA. This patch also fixes a bug where the lcd would not power down when blanking. Further this patch fixes an indentation issue. The comment line uses eight whitespace and is replaced with a hard tab. gpio_request + gpio_direction_output are replaced with gpio_request_one. The return value of gpio_request_one is used to set the value of the gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the unsuccessful request. But already successful requested gpios are not freed.

Rather than forcing the state of MPU powerdomain to on, simply read the current value and restore it after the ROM code has run.

Also delete conditional reference to ixp4xx_get_board_tick_rate() which is not defined anywhere. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>

Unfortunately, calling a function means using the stack, and the stack pointer was not initialized in the 32-bit setup code! This code initializes the stack pointer, and simplifies the interface slightly since it is easier to rely on just a pointer value rather than a descriptor; we need to have different values for the segment register anyway. This retains start_stack as a virtual address, even though a physical address would be more convenient for 32 bits; the 64-bit code wants the other way around...
