common: Move CONFIG_BOOTARGS to Kconfig

2017-08-14T21:06:06+00:00

Also introduce CONFIG_USE_BOOTARGS option so we can control if
CONFIG_BOOTARGS defined at all.

nvme: Add NVM Express driver support

2017-08-13T19:17:31+00:00

NVM Express (NVMe) is a register level interface that allows host
software to communicate with a non-volatile memory subsystem. This
interface is optimized for enterprise and client solid state drives,
typically attached to the PCI express interface.

This adds a U-Boot driver support of devices that follow the NVMe
standard [1] and supports basic read/write operations.

Tested with a 400GB Intel SSD 750 series NVMe card with controller
id 8086:0953.

rockchip: rk3368: add DRAM controller driver with DRAM initialisation

2017-08-13T15:12:33+00:00

This adds a DRAM controller driver for the RK3368 and places it in
drivers/ram/rockchip (where the other DM-enabled DRAM controller
drivers for rockchip devices should also be moved eventually).

At this stage, only the following feature-set is supported:
 - DDR3
 - 32-bit configuration (i.e. fully populated)
 - dual-rank (i.e. no auto-detection of ranks)
 - DDR3-1600K speed-bin

This driver expects to run from a TPL stage that will later return to
the RK3368 BROM.  It communicates with later stages through the
os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR
init code).

Unlike other DMC drivers for RK32xx and RK33xx parts, the required
timings are calculated within the driver based on a target frequency
and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this
time).

The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0)
register for controlling the operation of its (single-channel) DRAM
controller in the GRF block.  This provides for selecting DDR3, mobile
DDR modes, and control low-power operation.
As part of this change, DDRC0_CON0 is also added to the GRF structure
definition (at offset 0x600).

rockchip: back-to-bootrom: split BACK_TO_BOOTROM for TPL/SPL

2017-08-13T15:12:19+00:00

The back-to-bootrom option is rather unfortunately named
  CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM
instead of
  CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM

To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM),
we need to rename it.  At the same time, we introduce a TPL_ variant of
the option to give us finer-grained control over when it should be used.

This change is motivated by our RK3368 boot process, which returns to
the boot ROM only from the TPL stage, but not from the SPL stage.

GPT: provide commands to selectively rename partitions

2017-08-05T00:35:27+00:00

This patch provides support in u-boot for renaming GPT
partitions.  The renaming is accomplished via new 'gpt swap'
and 'gpt rename' commands.

The 'swap' mode returns an error if no matching partition names
are found, or if the number of partitions with one name does not equal
the number with the second name.   The 'rename' variant always
succeeds as long as a partition with the provided number exists.

Rewriting the partition table has the side-effect that all partitions
end up with "msftdata" flag set.  The reason is that partition type
PARTITION_BASIC_DATA_GUID is hard-coded in the gpt_fill_pte()
function.  This does not appear to cause any harm.

GPT: add accessor function for disk GUID

2017-08-04T13:56:04+00:00

In order to read the GPT, modify the partition name strings, and then
write out a new GPT, the disk GUID is needed.  While there is an
existing accessor for the partition UUIDs, there is none yet for the
disk GUID.
