f26c8a8e77 dm: Add a clock uclass
Clocks are an important feature of platforms and have become increasing
complex with time. Most modern SoCs have multiple PLLs and dozens of clock
dividers which distribute clocks to on-chip peripherals.

Some SoC implementations have a clock API which is private to that SoC family,
e.g. Tegra and Exynos. This is useful but it would be better to have a
common API that can be understood and used throughout U-Boot.

Add a simple clock API as a starting point. It supports querying and setting
the rate of a clock. Each clock is a device. To reduce memory and processing
overhead the concept of peripheral clocks is provided. These do not need to
be explicit devices - it is possible to write a driver that can adjust the
I2C clock (for example) without an explicit I2C clock device. This can
dramatically reduce the number of devices (and associated overhead) in a
complex SoC.

Clocks are referenced by a number, and it is expected that SoCs will define
that numbering themselves via an enum.

6c51df6859 dm: Add support for RAM drivers
Add support for a driver which sets up DRAM and can return information about
the amount of RAM available. This is a first step towards moving RAM init

5917112c9e dm: Add support for LEDs
Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.

This implementation requires a driver for each type of LED (e.g GPIO, I2C).

11f4dc1583 dm: Implement a CPU uclass
It is useful to be able to keep track of the available CPUs in a multi-CPU
system. This uclass is mostly intended for use with SMP systems.

The uclass provides methods for getting basic information about each CPU.

a43febde44 soc: keystone_serdes: create a separate SGMII SerDes driver
This patch split the Keystone II SGMII SerDes related code from
Ethernet driver and create a separate SGMII SerDes driver.
The SerDes driver can be used by others keystone subsystems
like PCI, sRIO, so move it to driver/soc/keystone directory.

Add soc specific drivers directory like in the Linux kernel.
It is going to be used by keysotone soc specific drivers.

f494e0a184 kbuild: refactor some makefiles
[1] Move driver/core/, driver/input/ and drivers/input/ entries
    from the top Makefile to drivers/Makefile

[2] Remove the conditional by CONFIG_DM in drivers/core/Makefile
    because the whole drivers/core directory is already selected
    by CONFIG_DM in the upper level

[3] Likewise for CONFIG_DM_DEMO in drivers/demo/Makefile

[4] Simplify common/Makefile - both CONFIG_DDR_SPD and
    CONFIG_SPD_EEPROM are boolean macros so they can directly
    select objects

63cec5814f Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts.
All of the PCI/PCI-Express driver and initialization code that
was in the MPC8641HPCN port has now been moved into the common
drivers/fsl_pci_init.c.  In a subsequent patch, this will be
utilized by the 85xx ports as well.

Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added.

Also enable the second PCI-Express controller on 8641
by getting its BATS and CFG_ setup right.

Fixed a u16 vendor compiler warning in AHCI driver too.

66d9dbec1c Add driver for S-ATA-controller on Intel processors with South
Bridge, ICH-5, ICH-6 and ICH-7. 

Implementation:

1. Code is divided in to two files. All functions, which are
   controller specific are kept in "drivers/ata_piix.c" file and
   functions, which are not controller specific, are kept in
   "common/cmd_sata.c" file.

2. Reading and Writing from the S-ATA drive is done using PIO method.

3. Driver can be configured for 48-bit addressing by defining macro
   CONFIG_LBA48, if this macro is not defined driver uses the 28-bit
   addressing.

4. S-ATA read function is hooked to the File system, commands like
   ext2ls and ext2load file can be used. This has been tested.

5. U-Boot command "SATA_init" is added, which initializes the S-ATA
   controller and identifies the S-ATA drives connected to it.

6. U-Boot command "sata" is added, which is used to read/write, print
   partition table and get info about the drives present. This I have
   implemented in same way as "ide" command is implemented in U-Boot.

7. This driver is for S-ATA in native mode.

8. This driver does not support the Native command queuing and
   Hot-plugging.
