2016-05-02Revert "omap3: Use raw SPL by default for mmc1"Tom Rini
Unfortunately with this change we now are unable to do FS mode boots from MMC1 as with the way the code works today we will always load and assume that the hard-coded raw location contains U-Boot. Further, we cannot fix this by just changing other logic to try FS-then-RAW as it would also make us have to ignore what order the ROM is telling us to try. This reverts commit 22d90d560a2b01c47f180e196e6c6485eb8e65db. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-05-01ARM: uniphier: move pin-mux code into pin_init functionMasahiro Yamada
The code in uniphier_sld3_sbc_init() is pin-muxing, so it would be a better fit in uniphier_sld3_early_pin_init(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

The System Bus is not available by default on the ROM boot mode of PH1-LD20. To use devices connected to the System Bus, such as the Micro Support Card, it is necessary to set up pin-muxing and some System Bus Controller register. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-04-27sunxi: mctl_mem_matches: Add missing memory barrierHans de Goede
We are running with the caches disabled when mctl_mem_matches gets called, but the cpu's write buffer is still there and can still get in the way, add a memory barrier to fix this. This avoids mctl_mem_matches always returning false in some cases, which was resulting in: U-Boot SPL 2015.07 (Apr 14 2016 - 18:47:26) DRAM: 1024 MiB U-Boot 2015.07 (Apr 14 2016 - 18:47:26 +0200) Allwinner Technology CPU: Allwinner A23 (SUN8I) DRAM: 512 MiB Where 512 MiB is the right amount, but the DRAM controller would be initialized for 1024 MiB.

2016-04-25ARM: DRA7: Add ABB setup for all domainsNishanth Menon
ABB should be initialized for all required domains voltage domain for DRA7: IVA, GPU, EVE in addition to the existing MPU domain. If we do not do this, kernel configuring just the frequency using the default boot loader configured voltage can fail on many corner lot units and has been hard to debug. This specifically is a concern with DRA7 generation of SoCs since other than VDD_MPU, all other domains are only permitted to setup the voltages to required OPP only at boot.

2016-04-25ARM: OMAP5: Enable ABB configuration for MM voltage domainNishanth Menon
Since we setup the voltage and frequency for the MM domain, we *must* setup the ABB configuration needed for the domain as well. If we do not do this, kernel configuring just the frequency using the default boot loader configured voltage can fail on many corner lot units.

2016-04-25ARM: OMAP5/DRA7: Move ABB TXDONE mask to voltage structureNishanth Menon
ABB TX_DONE mask will vary depending on ABB module. For example, 3630 never had ABB on IVA domain, while OMAP5 does use ABB on MM domain, DRA7 has it on all domains with the exception of CORE, RTC. Hence, move the txdone mask definition over to structure describing voltage domain. Signed-off-by: Nishanth Menon <nm@ti.com>
2016-04-25ARM: OMAP5/DRA7: Get rid of control_std_fuse_opp_vdd_mpu_2Nishanth Menon
This information is already available under vcores->volts.efuse.reg. There is no reason for duplicating the information since AVS Class 0 definitions are common for OMAP5 and DRA7 and defined with STD_FUSE_OPP_* macros. This allows a central location of defining the ABB and voltage definitions especially since they are reused. This also makes it simpler to prevent mistakes involved when changing the boot OPP for the device. Signed-off-by: Nishanth Menon <nm@ti.com>

2016-04-24ARM: uniphier: rework uniphier_set_fdt_file()Masahiro Yamada
The current table look-up for the DTB file name turned out bothersome in terms of maintainability; I ended up adding a new entry every time a new board is supported. There is a common pattern between the DT compatible string and the corresponding file name; drop the vendor prefix "socionext," and prefix it with "uniphier-" and suffix it with ".dtb".

2016-04-19imx: mx6: Fix procedure to switch the parent of LDB_DI_CLKAkshay Bhat
Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk tree, the glitchy parent mux of ldb_di[x]_clk can cause a glitch to enter the ldb_di_ipu_div divider. If the divider gets locked up, no ldb_di[x]_clk is generated, and the LVDS display will hang when the ipu_di_clk is sourced from ldb_di_clk. To fix the problem, both the new and current parent of the ldb_di_clk should be disabled before the switch. This patch ensures that correct steps are followed when ldb_di_clk parent is switched in the beginning of boot. This patch was ported from the 3.10.17 NXP kernel http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/commit/?h=imx_3.10.17_1.0.1_ga&id=eecbe9a52587cf9eec30132fb9b8a6761f3a1e6d NXP errata number: ERR009219, EB821 Signed-off-by: Akshay Bhat <akshay.bhat@timesys.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@nxp.com>
2016-04-19arm: mx5: Fix NAND image generationMarek Vasut
The echo -ne "\xNN" does not work in certain bourne-compatible shells, like dash. The recommended way of hex->char conversion is using printf(1), but there is a pitfall here. The GNU printf does support "\xNN" format, but according to the opengroup documentation, this is not part of POSIX. The POSIX printf only defines "\NNN" where N is octal. Thus, for the sake of compatibility, we use that. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de>
2016-04-18ARM: always perform per-CPU GIC initStephen Warren
The current code in ARMv8's lowlevel_init() skips the per-CPU GIC initialization ifndef CONFIG_ARMV8_MULTIENTRY. However, the per-CPU init should always occur; it's just the one-time init that should only happen on the master. Once this consideration is taken into account, the only difference between the paths when CONFIG_ARMV8_MULTIENTRY is undefined/defined is the use of branch_if_slave. Naively, any unified code would need to invoke this conditionally upon ifdef CONFIG_ARMV8_MULTIENTRY. However, branch_if_slave already checks CONFIG_ARMV8_MULTIENTRY and does nothing if it isn't defined, so we don't even need that ifdef at the call site.
