* s3cmci: add better support for no card detect or write protect availableBen Dooks2009-10-011-0/+2
| | | | | | | | | | | | | | | Add better support for omitting either the card detect or the write protect GPIOs if the board does not support it. Add the fields no_wprotect and no_detect to the platform data which when set indicate the absence of the respective GPIOs. Note, this also fixes a minor bug where it tries to free IRQ0 if there is no detect gpio available.

* s3cmci: Kconfig selection for PIO/DMA/BothBen Dooks2009-10-011-0/+1
| | | | | | | | | | | | | | Add a selection for the data transfer mode of the s3cmci driver, allowing for either a configuration or rumtime selection of the use of the DMA or PIO transfer code. The PIO only mode is 476 bytes smaller than the driver with both methods compiled in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only way to flush posted write to L4 bus is to do a read back of the same register right after the write. This seems to be mostly needed in interrupt handlers to avoid causing spurious interrupts. The earlier fix has been to mark the L4 bus as strongly ordered memory, which solves the problem, but causes performance penalties.

When a request is made to run async_pq against more than the hardware maximum number of supported sources we need to reuse the previous generated P and Q values as sources into the next operation. Care must be taken to remove Q from P' and P from Q'. For example to perform a 5 source pq op with hardware that only supports 4 sources at a time the following approach is taken: p, q = PQ(src0, src1, src2, src3, COEF({01}, {02}, {04}, {08})) p', q' = PQ(p, q, q, src4, COEF({00}, {01}, {00}, {10})) p' = p + q + q + src4 = p + src4 q' = {00}*p + {01}*q + {00}*q + {10}*src4 = q + {10}*src4 Note: 4 is the minimum acceptable maxpq otherwise we punt to synchronous-software path. The DMA_PREP_CONTINUE flag indicates to the driver to reuse p and q as sources (in the above manner) and fill the remaining slots up to maxpq with the new sources/coefficients. Note1: Some devices have native support for P+Q continuation and can skip this extra work. Devices with this capability can advertise it with dma_set_maxpq. It is up to each driver how to handle the DMA_PREP_CONTINUE flag. Note2: The api supports disabling the generation of P when generating Q, this is ignored by the synchronous path but is implemented by some dma devices to save unnecessary writes. In this case the continuation algorithm is simplified to only reuse Q as a source. Cc: H.

This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

Normally one would expect to find a call to cpu_do_idle() there, but that call is disabled, even though cpu_do_idle() is implemented for XScale cores (and ixp4xx is one). The explanation can be found in the ixp42x developer's manual which states that the XScale core clock and power management registers aren't implemented on ixp42x [3.5.2.2]. Also, the disabled code has suffered from bit rot: - it checks hlt_counter which is obsolete, as that variable and all related code now is private to kernel/process.c - it passes too many parameters to cpu_do_idle() So this patch: - adds a comment before the #if 0 to explain why cpu_do_idle() mustn't be called on ixp4xx - removes the obsolete test of hlt_counter and the obsolete parameter to cpu_do_idle() This is purely a documentation fixup and changes no generated code. Even so, it has been tested on an ixp420 machine (ds101). Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
