      davinci: Support JTAG ID register at any address · 1117960c
      Mark A. Greer authored 
      The Davinci cpu_is_davinci_*() macros use the SoC part number
and variant retrieved from the JTAG ID register to determine the
type of cpu that the kernel is running on.  Currently, the code to
read the JTAG ID register assumes that the register is always at
the same base address.  This isn't true on some newer SoCs.

To solve this, have the SoC-specific code set the JTAG ID register
base address in soc_info structure and add a 'cpu_id' member to it.
'cpu_id' will be used by the cpu_is_davinci_*() macros to match
the cpu id.  Also move the info used to identify the cpu type into
the SoC-specific code to keep all SoC-specific code together.

The common code will read the JTAG ID register, search through
an array of davinci_id structures to identify the cpu type.
Once identified, it will set the 'cpu_id' member of the soc_info
structure to the proper value and the cpu_is_davinci_*() macros
will now work.

      davinci: Encapsulate SoC-specific data in a structure · a33f8b29
      Mark A. Greer authored 
      Create a structure to encapsulate SoC-specific information.
This will assist in generalizing code so it can be used by
different SoCs that have similar hardware but with minor
differences such as having a different base address.

The idea is that the code for each SoC fills out a structure
with the correct information.  The board-specific code then
calls the SoC init routine which in turn will call a common
init routine that makes a copy of the structure, maps in I/O
regions, etc.

After initialization, code can get a pointer to the structure
by calling davinci_get_soc_info().  Eventually, the common
init routine will make a copy of all of the data pointed to
by the structure so the original data can be made __init_data.
That way the data for SoC's that aren't being used won't consume
memory for the entire life of the kernel.

The structure will be extended in subsequent patches but
initially, it holds the map_desc structure for any I/O
regions the SoC/board wants statically mapped.

      NET: DaVinci EMAC: NAPI updates for 2.6.30 · 5be767db
      Chaithrika U S authored 
      Fix EMAC driver build errors for 2.6.30-rc2 staging branch

The member 'bus_id'  no longer exists in the device structure,
instead use dev_name() function. Also, replace netif_rx_schedule()
and netif_rx_complete() with napi_schedule() and napi_complete()
respectively.

Tested on TI DM644x and DM646x EVMs.

      ARM: DaVinci: emac: move random_ether_addr to davinci_emac · 0b9273a3
      Troy Kisky authored 
      Move the creation of a random ethernet address from devices.c
into davinci_emac.c. This allows me to delete the davinci_emac_init
function and directly call the dmxxx specific function from the
board file.
