linux-toradex.git/arch/arm/mach-iop32x, branch Rel3 Linux kernel for Apalis and Colibri modules ARM: zImage: remove the static qualifier from global data variables 2011-05-07T04:08:02+00:00 Nicolas Pitre nicolas.pitre@linaro.org 2011-04-28T21:00:17+00:00 8ea0de4b8831513924e3ec6a17bb721fabf97055 To be able to relocate the .bss section at run time independently from the rest of the code, we must make sure that no GOTOFF relocations are used with .bss symbols. This usually means that no global variables can be marked static unless they're also const. Let's remove the static qualifier from current offenders, or turn them into const variables when possible. Next commit will ensure the build fails if one of those is reintroduced due to otherwise enforced coding standards for the kernel.

arm: return both physical and virtual addresses from addruart 2010-10-20T04:27:33+00:00 Jeremy Kerr jeremy.kerr@canonical.com 2010-07-06T10:30:06+00:00 0ea1293009826da45e1019f45dfde1e557bb30df Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.

ARM: 5943/1: iop: n2100: enable serial interrupt 2010-04-29T17:03:49+00:00 Aaro Koskinen aaro.koskinen@nokia.com 2010-02-16T21:06:14+00:00 cc761beda2426cf663a649b905b6643673ff7b30 Thecus N2100 has a jumper (J3/J4) to select whether the XINT1 interrupt line is connected to the second UHCI controller (position J3) or to the serial port UART (position J4). Currently, the kernel is hardcoded to assume the J3 position, and the serial port is always being used in polling mode. The patch adds the IRQ autodetection flag for the serial port interrupt, and also marks it as shared (as the driver for the second UHCI controller will request the interrupt in any case). Now, when the jumper is set to the J4 position, the serial port will have an interrupt line, resulting in less CPU overhead and faster throughput.
