2015-07-01arc: significant cache reworkAlexey Brodkin
[1] Align cache management functions to those in Linux kernel. I.e.: a) Use the same functions for all cache ops (D$ Inv/Flush) b) Split cache ops in 3 sub-functions: "before", "lineloop" and "after". That way we may re-use "before" and "after" functions for region and full cache ops. [2] Implement full-functional L2 (SLC) management. Before SLC was simply disabled early on boot. It's also possible to enable or disable L2 cache from config utility. [3] Disable/enable corresponding caches early on boot. So if U-Boot is configured to use caches they will be used at all times (this is useful in partucular for speed-up of relocation). Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-07-01arc: implement slave cores kick-start for Linux kernelAlexey Brodkin
With new SMP-enabled CPUs with ARC HS38 cores and corresponding support in Linux kernel it's required to add basic SMP support in U-Boot. Currently we assume the one and only core starts execution after power-on. So most of things in U-Boot is handled in UP mode. But when U-Boot is used for loading and starting Linux kernel right before jumping to kernel's entry point U-Boot: [1] Sets all slave cores to jump to the same address [kernel's entry point] [2] Really starts all slav cores In ARC's implemetation of SMP in Linux kernel all cores are supposed to run the same start-up code. But only core with ID 0 (master core) processes further while others are looping waiting for master core to complete some initialization. That means it's safe to un-pause slave cores and let them execute kernel - they will wait for master anyway.

2015-06-25Move default y configs out of arch/board KconfigJoe Hershberger
Some archs/boards specify their own default by pre-defining the config which causes the Kconfig system to mix up the order of the configs in the defconfigs... This will cause merge pain if allowed to proliferate. Remove the configs that behave this way from the archs.

2015-06-19ARM: DRA7: Change configuration to prevent DDR reset control from EMIFNishanth Menon
DRA7/AM57xx devices can be operated in many different configurations. When the SoC is supposed to support a configuration where low power mode state may involve the SoC completely powered off and DDR is in self refresh, SoC EMIF controller should not be the master of the reset signal and an external entity might be in control of things. The default configuration of Linux on TI evms involve not powering off the voltage rails (due to various reasons including reliability concerns) and must not allow DDR reset to be controlled by EMIF. On platforms where external entity might control the reset signal, this configuration will be a "dont care".

In addition to the regular mux configuration, certain pins of DRA7 require to have "manual mode" also programmed, when predefined delay characteristics cannot be used for the interface. struct iodelay_cfg_entry is introduced for populating manual mode IO timings. For configuring manual mode, along with the normal pad configuration do the following steps: - Select MODESELECT field of each assocaited PAD. CTRL_CORE_PAD_XXX[8]:MODESELECT = 1(Enable MANUAL_MODE macro along with mux) - Populate A_DELAY, G_DELAY values that are specified in DATA MANUAL.

2015-06-12ARM: DRA7: Add support for IO delay configurationLokesh Vutla
On DRA7, in addition to the regular muxing of pins, an additional hardware module called IODelay which is also expected to be configured. This "IODelay" module has it's own register space that is independent of the control module. It is advocated strongly in TI's official documentation considering the existing design of the DRA7 family of processors during mux or IODelay recalibration, there is a potential for a significant glitch which may cause functional impairment to certain hardware. It is hence recommended to do muxing as part of IOdelay recalibration. IODELAY recalibration sequence: - Complete AVS voltage change on VDD_CORE_L - Unlock IODLAY config registers. - Perform IO delay calibration with predefined values. - Isolate all the IOs - Update the delay mechanism for each IO with new calibrated values. - Configure PAD configuration registers - De-isolate all the IOs. - Relock IODELAY config registers.
