ARM: realview: basic device tree implementation This implements basic device tree boot support for the RealView platforms, with a basic device tree for ARM PB1176 as an example. The implementation is done with a new DT-specific board file using only pre-existing bindings for the basic IRQ, timer and serial port drivers. A new compatible type is added to the GIC for the ARM1176. This implementation uses the MFD syscon handle from day one to access the system controller registers, and register the devices using the SoC bus.

ARM: realview: add an DT SMP boot method This adds an SMP boot method for the ARM RealView reference designs. We also select HAVE_SMP by default and make it use SMP_ON_UP so we only need to support one single kernel across the RealView reference designs when using DT. The RealViews need to have the SCU (Snoop Control Unit) activated on boot, and this is now done by looking up its address from the device tree and initializing it and counting the available cores. The RealViews boot by using a magic address register in the system controller (SYS_FLAGS) to store the boot address, the ROM will then read this register to the PC when the CPUs are taken out of WFI. This code uses a handle to the syscon regmap to access this register. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ARM: Push selects for TWD/SCU into machine entries The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

ARM: config: sort select statements alphanumerically As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

ARM: Push selects for TWD/SCU into machine entries The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

To enable this, a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow machines to indicate that they may have such a cache controller independently of each other. Boards/SoCs which cannot reliably operate without the L2 cache controller support will need to select CACHE_L2X0 directly from their own Kconfigs instead. This applies to some TrustZone-enabled boards where Linux runs in the Normal World, for example.

ARM: realview: name configuration options after actual board names As no one seems to really know which configuration options tie up with which boards, I thought I'd do some investigation and try to work it out. After discussion with some folk in linaro, I think I have this nailed. The names are updated to use the name on the front of the appropriate board user guide for the various baseboards, which I've taken to be the official name for each board. I haven't significantly updated the descriptions for the tiles as that is even less clear - as far as I can see on ARMs website, there is no Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S, ARM1176TZF-S and Cortex-R4F.
