2015-02-10arm: mxs: Add 'Wait for JTAG user' if booted in JTAG modeGraeme Russ
When booting in JTAG mode, there is no way to use soft break-points, and no way of knowing when SPL has finished executing (so the user can issue a 'halt' command to load u-boot.bin for example) Add a debug output and simple loop to stop execution at the completion of the SPL initialisation as a pseudo break-point when booting in JTAG mode Signed-off-by: Graeme Russ <gruss@tss-engineering.com>
2015-02-10arm: mxs: Enable booting of mx28 without batteryGraeme Russ
Section 4.1.2 of Freescale Application Note AN4199 describes the configuration required to operate the mx28 from a 5V source without a battery. This patch changes the behaviour of the dropout control of the DC-DC converter (refer to section 11.12.9 of the mx28 Application Processor Reference Manual - Document Number: MCIMX28RM, Rev 2, 08/2013) to the following: - Always use 4P2 Linear Regulator if CONFIG_SYS_MXS_VDD5V_ONLY is defined - Switch between 4P2 Linear Regulator and Battery, using whichever has the highest voltage if CONFIG_SYS_MXS_VDD5V_ONLY isnot set (this is the same as the pre-patch behaviour) Signed-off-by: Graeme Russ <gruss@tss-engineering.com> Signed-off-by: Damien Gotfroi <dgotfroi@greenwatch.be>
2015-02-10arm: mxs: Add debug outputs and comments to mxs SPL source filesGraeme Russ
It is difficult to track down fail to boot issues in the mxs SPL. Implement the following to make it easier: - Add debug outputs to allow tracing of SPL progress in order to track where failure to boot occurs. DEUBUG and CONFIG_SPL_SERIAL_SUPPORT must be defined to enable debug output in SPL - Add TODO comments where it is not clear if the code is doing what it is meant to be doing, even tough the board boots properly (these comments refer to existing code, not to any code added by this patch) Signed-off-by: Graeme Russ <gruss@tss-engineering.com>
2015-02-10imx: mx6: Fixed AIPS3 base address issueYe.Li
Should use AIPS3 configuration address 0x0227C000 to set AIPS3, not the AIPS3 base address. Additional, replace AIPS1_BASE_ADDR to AIPS3_ARB_BASE_ADDR to align with AIPS1 and AIPS2, and resolve the AIPS3_ARB_BASE_ADDR undefine problem. Signed-off-by: Ye.Li <B37916@freescale.com>

2015-02-06arm: armada-xp: Add SPL support used to include the DDR training codeStefan Roese
This patch adds SPL support to the Marvell Armada-XP. With this addition the bin_hdr integration is not needed any more. The SPL will first initialize the serdes/PHY and the call the DDR setup and training code now integrated into mainline U-Boot.

2015-02-07ARM: UniPhier: leave the last element of boot_device_table emptyMasahiro Yamada
Checking if the pointer is NULL would be easier to know the tail of the boot_device_table[] array. For clarification, add the /* sentinel */ comment. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2015-02-07ARM: UniPhier: refactor pinmon commandMasahiro Yamada
The return value of get_boot_mode_sel() is used as the index of the boot_device_table[] array. Its type should be "int" rather than "u32". Use only the iterator "i" for the loop in do_pinmon(). Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2015-02-07ARM: UniPhier: do not compile unnecessary objectsMasahiro Yamada
It is true that unused functions are removed from the ELF image by the compiler's garbage collection but relying on it too much does not look nice. Currently, the build is taking more than it should. Refactor the makefiles to compile only files that are really needed. CONFIG_SOC_INIT and CONFIG_DRAM_INIT are no longer needed by the optimization. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2015-02-07ARM: UniPhier: remove unused checkboard() functionsMasahiro Yamada
Since commit 0365ffcc0bd6 (generic-board: show model name in board_init_f() too), checkboard() is invoked only when show_board_info() fails to get the model name from Device Tree. It never happens because UniPhier SoCs now only work with CONFIG_OF_CONTROL and all the root nodes of UniPhier device trees have the "model" property. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2015-02-07ARM: UniPhier: revive support card infoMasahiro Yamada
Since commit 0365ffcc0bd6 (generic-board: show model name in board_init_f() too), the support card information has not been displayed because check_support_card() is invoked only when show_board_info() fails to get the model name from Device Tree. This commit adds misc_init_f() function to call check_support_card() from there. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2015-02-07ARM: UniPhier: move SPL init functions to spl_board_init()Masahiro Yamada
Now init functions called from board_postclk_init() and dram_init() are only necessary for SPL. Move them to spl_board_init() for clean-up. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2015-02-07ARM: UniPhier: move pin_init() to board_early_init_f()Masahiro Yamada

2015-01-29ARM: OMAP5: DRA7xx: Add support for power rail groupingLubomir Popov
On the DRA72x (J6Eco) EVM one PMIC SMPS is powering three SoC core rails. This concept of using one SMPS to supply multiple core domains (in various, although limited combinations, per primary device use case) has now become common and is used by many customer J6/J6Eco designs; it is supported by a number of corresponding PMIC OTP versions. This patch implements correct operation of the core voltages scaling routine by ensuring that each SMPS that is supplying more than one domain shall be written only once, and with the highest voltage of those fused in the SoC (or of those defined in the corresponding header if fuse read is disabled or fails) for the power rails belonging to the group. The patch also replaces some PMIC-related magic numbers with the appropriate definitions. The default OPP_NOM voltages for the DRA7xx SoCs are updated as well, per the latest DMs. Signed-off-by: Lubomir Popov <l-popov@ti.com>

2015-01-26ARM: zynq: Enable the Neon instructionsMichal Simek
Added the lowlevel_init to enable the Neon instructions. Initially the u-boot was causing undefined instruction exception if loaded through tcl, and working fine if loaded through FSBL. The exception was causing in convertion formula of given time to ticks. It was because, the Neon instructions were disabled and hence causing the undefined exception. In FSBL case, the FSBL was enabling the Neon instructions. Hence, added the lowlevel_init to enable the Neon instructions. Also enable neon instructions for non-xilinx toolchain.

2015-01-21sunxi: Restore lowlevel_init usageHans de Goede
2 recent sunxi changes have removed the usage of lowlevel_init by moving some code around and then setting CONFIG_SKIP_LOWLEVEL_INIT. This is problematic for 2 reasons: 1) It does not just stop s_init from being called, it also stops cpu_init_cp15 from getting called, which is undesirable. 2) We want u-boot.bin to be usable standalone, without SPL, some people e.g. use an upstream u-boot.bin together with Allwinner's boot0 loader. So u-boot.bin must (re)initialize the gpios, timer, etc. This commit restores the lowlevel_init / s_init usage, while keeping the changes to no longer use the global-data (gd) struct in the SPL.
