2014-06-18arm64: defconfig update for LTPCatalin Marinas1-0/+15
This patch adds several defconfig options required primarily by the LTP test suite. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2014-05-22arm64: defconfig: enable a few more common/useful options in defconfigWill Deacon1-13/+23
Whilst our defconfig is certainly usable, there are a few extra features we can enable to make it considerably more useful, particularly if people are using it for testing: - KVM - SWAP - Hugepages - ARMv8 crypto This patch enables these options in our defconfig. Note that the ordering has changed slightly, since this is the result of a new savedefconfig make target.

2014-02-07arm64: defconfig: Expand default enabled featuresMark Rutland1-4/+14
FPGA implementations of the Cortex-A57 and Cortex-A53 are now available in the form of the SMM-A57 and SMM-A53 Soft Macrocell Models (SMMs) for Versatile Express. As these attach to a Motherboard Express V2M-P1 it would be useful to have support for some V2M-P1 peripherals enabled by default. Additionally a couple of of features have been introduced since the last defconfig update (CMA, jump labels) that would be good to have enabled by default to ensure they are build and boot tested. This patch updates the arm64 defconfig to enable support for these devices and features. The arm64 Kconfig is modified to select HAVE_PATA_PLATFORM, which is required to enable support for the CompactFlash controller on the V2M-P1. A few options which don't need to appear in defconfig are trimmed: * BLK_DEV - selected by default * EXPERIMENTAL - otherwise gone from the kernel * MII - selected by drivers which require it * USB_SUPPORT - selected by default Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-11-05arm64: defconfig: Enable CONFIG_PREEMPT by defaultCatalin Marinas1-1/+1
This way we can spot early bugs when just testing with the default config. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2013-09-30arm64: include VIRTIO_{MMIO,BLK} in defconfigRamkumar Ramachandra1-1/+3
Currently, development on arm64 is aided by a Foundation_v8 emulator distributed by ARM [1]. To run their kernels, users will execute: $ ./Foundation_v8 --image linux-system.axf --block-device raring-rootfs To mount the raring-rootfs filesystem, the kernel parameter should typically include: root=/dev/vda For this device to be present, the kernel must be compiled with VIRTIO_{MMIO,BLK}. To make this work out-of-the-box, make it part of the default configuration.

2013-09-30arm64: include EXT4 in defconfigRamkumar Ramachandra1-0/+1
Most readily available root filesystems are formatted as EXT4 these days. For example, see the raring rootfs that the Debian folk is preparing [1].

2013-04-26arm64: vexpress: Enable ARMv8 RTSM model (SoC) supportCatalin Marinas1-0/+4
This patch adds the necessary Kconfig entries to enable support for the ARMv8 software model (Versatile Express platform) together with the defconfig update. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
2013-03-19arm64: Kconfig.debug: Remove unused CONFIG_DEBUG_ERRORSPaul Bolle1-1/+0
The Kconfig entry for DEBUG_ERRORS is a verbatim copy of the former arm entry for that symbol. It got removed in v2.6.39 because it wasn't actually used anywhere. There are still no users of DEBUG_ERRORS so remove this entry too.
