2015-02-13Exynos: Clock: Cleanup soc_get_periph_rateAkshay Saraswat
Since we have src, div and pre-div mask bits defined corresponding to peripherals, calculation of clock specific to I2C appears redundant and confusing. Using clk_bit_info struct we can write calculations generic to all peripherals which makes code easy to understand and free from peripheral specific exceptions.

2015-02-13Exynos: clock: change mask bits as per peripheralAkshay Saraswat
We have assumed and kept mask bits for divider and pre-divider as 0xf and 0xff, respectively. But these mask bits change from one peripheral to another, and hence, need to be specified in accordance with the peripherals.

2015-02-13Exynos5: Use clock_get_periph_rate generic APIAkshay Saraswat
Replacing SoC and peripheral specific function calls with generic clock_get_periph_rate calls to get the peripheral clocks. Also, removing dead code of peripheral and SoC specific function implementations which was used earlier for fetching peripheral clocks. This code is not being used anymore because of the introduction of generic clock_get_periph_rate function.

2015-02-13Exynos5: Fix exynos5_get_periph_rate calculationsAkshay Saraswat
exynos5_get_periph_rate function reads incorrect div for SDMMC2 & 3. It also reads prediv and does division only for SDMMC0 & 2 when actually various other peripherals need that. Adding changes to fix these mistakes in periph rate calculation.

2015-02-13Exynos542x: Add and enable get_periph_rate supportAkshay Saraswat
We planned to fetch peripheral rate through one generic API per peripheral. These generic peripheral functions are in turn expected to fetch apt values from a function refactored as per SoC versions. This patch adds support for fetching peripheral rates for Exynos5420 and Exynos5800.

2015-02-13Exynos542x: Move exynos5420_get_pll_clk up and renameAkshay Saraswat
Moving exynos5420_get_pll_clk function definition up in the code to keep it together with rest of SoC_get_pll_clk functions. This makes code more legible and also removes the need of declaration when called before the position of definition in code. Also, renaming exynos5420_get_pll_clk to exynos542x_get_pll_clk because it is being used for both Exynos 5420 and 5800.

2015-02-13Exynos5: Fix compiler warnings due to clock_get_periph_rateAkshay Saraswat
Apparently, members of clk_bit_info array do not map correctly to the members of enum periph_id. This mapping got broken after we changed periph_id(s) to reflect interrupt number instead of their position in a sequence. This patch intends to fix above mentioned issue.

2015-02-13arc: introduce U-Boot port for ARCv2 ISAAlexey Brodkin
ARC HS and ARC EM are new cores based on ARCv2 ISA which is binary incompatible with ISAv1 (AKA ARCompact). Significant difference between ISAv2 and v1 is implementation of interrupt vector table. In v1 it is implemented in the same way as on many other architectures - as a special location where user may put whether code executed in place (if machine word of space is enough) or jump to a full-scale interrupt handler. In v2 interrupt table is just an array of adresses of real interrupt handlers. That requires a separate section for IVT that is not encoded as code by assembler. This change adds support for following cores: * ARC EM6 (simple 32-bit microcontroller without MMU) * ARC HS36 (advanced 32-bit microcontroller without MMU) * ARC HS38 (advanced 32-bit microcontroller with MMU) As a part of ARC HS38 new version of MMU (v4) was introduced. Also this change adds AXS131 board which is the same DW ARC SDP base board but with ARC HS38 CPU tile. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

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>

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>
