Clarify the symbol by naming it MTD_RAW_NAND instead.

On some ARM big.LITTLE architecutres (Exynos 5433) the overhead is really big. The overhead can be measures using hackbench which will speed up by x3 times (11sec -> 3.4sec). When you check transaction on cache or buses, the results are way higher than normal for the same hackbench test: L1d cache invalidations: 26mln vs 4mln L2u cache invalidations: 42mln vs 12mln bus cyc/access: 30cyc/access vs. 20cyc/access context switch is x3 times cheaper Enable this option only when you have some locking issue to investigate.

Most of these have been covered and described in the other branches, we mostly keep defconfig separate to avoid conflicts between SoC/dt/driver updates that they otherwise would be grouped with. One thing worth mentioning here is that OMAP changes from using their own UART driver, to 8250, for the multi_v7_defconfig shared config on 32-bit. This means that the console is now named ttyS* instead of ttyO*. This change was already done for omap2_defconfig a while back, so most users of these configs have either already updated, or can easily follow the same patterns as they did at that time. This makes platform support slightly easier for distros, since they no longer need to keep track of a separate console prefix for these platforms" * tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (31 commits) Revert "arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO" arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO arm64: defconfig: Replace PINCTRL_MT7622 with PINCTRL_MTK_MOORE arm64: defconfig: Regenerate for v4.20 ARM: multi_v7_defconfig: Add TOSHIBA TC358764 bridge driver ARM: multi_v7_defconfig: Add MAX8952 regulator driver ARM: exynos_defconfig: Add TOSHIBA TC358764 bridge driver ARM: exynos_defconfig: Add MAX8952 regulator driver ARM: exynos_defconfig: Add MAX8998 RTC and charger drivers ARM: imx_v6_v7_defconfig: add imx7ulp support ARM: imx_v6_v7_defconfig: Select TOUCHSCREEN_GOODIX ARM: multi_v7_defconfig: enable STM32 analog & timer drivers arm64: defconfig: Enable GCC and PINCTRL for MSM8998 arm64: defconfig: Enable core Qualcomm SDM845 options ARM: defconfig: Enable the PL111 DRM driver on vexpress ARM: defconfig: Update the vexpress defconfig arm64: defconfig: Enable some qcom remoteproc configs arm64: defconfig: Enable QCS404 configs ARM: imx_v6_v7_defconfig: Enable USB_ANNOUNCE_NEW_DEVICES ARM: imx_v6_v7_defconfig: Enable BT_BNEP ... 2018-12-18T12:23:06+00:00 Peter Ujfalusi peter.ujfalusi@ti.com 2018-12-17T12:21:39+00:00 urn:sha1:3162b05fb74cd107b2a66f20485c62514b20048f Use the new options for default audio support and enable Nokia n900 audio as well.
