* [ARM] 4599/1: Preserve ATAG list for use with kexec (2.6.23)Mike Westerhof2007-10-123-1/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch resolves a kexec boot failure that can occur because no ATAGs are passed in to the kexec'd kernel. Currently the newly-kexec'd kernel may fail if it requires specific ATAGs, or it may fail because the fixed memory location at which it expects to find the ATAGs may contain random data instead of ATAGs. The patch ensures that any ATAGs passed to the current kernel at boot time are copied to a static buffer, and are copied back when kexec copies the new kernel into place. Thus the new kernel sees the same ATAGs from kexec and the boot loader. The boot parameters are copied without regard to type, content, or length -- this patch's scope is limited soley to saving and restoring a fixed-size block of memory containing the kernel's boot parameters. Additional functionality to examine, alter, or replace the ATAGs (using kexec, for example) can be implemented by manipulating the static buffer containing the preserved ATAGs. Note: the size of the buffer (1.5KB) is selected to comfortably hold one of each ATAG type, including a maximum-length command line and the maximum number of ATAG_MEM structures currently supported by the kernel. Should an ATAG list exceed that limit, the list will be silently truncated to that limit (to do other- wise at that point in the boot process would make a simple problem exceedingly complicated). [Note: this is the same patch as 4579, modified to accomodate the ATAG changes introduced in 2.6.23] Signed-off-by: Mike Westerhof <mwester at dls.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | The semantic of the REGSET macros didn't change, but hopefully it's more obvious as it's now. REGGET is changed to return the unshifted value, analogous to REGSET.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200. - Oneshot mode (used for NO_HZ and high res timers) uses the alarm to emulate a real oneshot timer; the trickiest bit is how to avoid some lowlevel races. Thanks to Remy Bohmer for various fixes to this code. - Tighten up periodic mode support using the PIT. - Streamline reads of the 32KHz counter. Thanks to Marc Pignat for some testing results: the CRTR register has *very* odd behavior. The reread appears to work around stranger glitches than just getting an old clock value (which would quickly self-correct). - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100), since that no longer acts correct (time increases too fast). Note that the at91sam9 and at91x40 chips need other solutions, since they don't have the same system timer module.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.

| * [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-1223-258/+513
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here.
