  setup_net_chip
   |--> gpio_direction_out
         |--> _set_gpio_dataout

In the previous patches, we introduced the SPL/TPL fraamework.
For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
the DDR according to the SPD and loads the final uboot image into DDR, then
jump to the DDR to begin execution.

For NAND booting way, the nand SPL has size limitation on some board(e.g.
P1010RDB), it can not be more than 8KB, we can call it "minimal SPL", So the
dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
and loads the final uboot image into DDR,then jump to the DDR to begin execution.

This patch enabled SPL/TPL for P1010RDB to support starting from NAND/SD/SPI
flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
execute, so the section .resetvec is no longer needed.

omap4_common: config: remove I2C for SPL mode

Commit 6789e84ecaa8f45d053084e08c381284a04abff7 (i2c, omap24xx:
convert driver to new mutlibus/mutliadapter framework) intended to
make I2C driver compatible with latest changes. It unfortunately has
had a impact on size on SPL as well. For example on SDP4430,
32032 bytes before/MLO
35416 bytes after/MLO

With this mentioned commit, MLO stops booting on SDP4430 as only 32K
is accessible for non-secure (bootloader) s/w on GP devices and the size
increase to 56K fails boot.

On the latest u-boot commit e7be18225fbea76d1f0034b224f0d1e60f07cfcf,
MLO is now at size 35592 bytes, However, I2C is not necessary for SPL
to function as we use SR_I2C for controlling the PMIC.
Disabling I2C reduces MLO to 32224 bytes which allows
OMAP4 GP platform to boot up.

Since this is common for all OMAP4 platforms, remove the need for I2C
for SPL builds in the common config.

Ionut Nicu [Tue, 4 Feb 2014 14:48:10 +0000 (15:48 +0100)]
ext4fs: Add ext4 extent cache for read operations

In an ext4 filesystem, the inode corresponding to a file has a 60-byte
area which contains an extent header structure and up to 4 extent
structures (5 x 12 bytes).

For files that need more than 4 extents to be represented (either files
larger than 4 x 128MB = 512MB or smaller files but very fragmented),
ext4 creates extent index structures. Each extent index points to a 4KB
physical block where one extent header and additional 340 extents could
be stored.

The current u-boot ext4 code is very inefficient when it tries to load a
file which has extent indexes. For each logical file block the code will
read over and over again the same blocks of 4096 bytes from the disk.

Since the extent tree in a file is always the same, we can cache the
extent structures in memory before actually starting to read the file.

This patch creates a simple linked list of structures holding information
about all the extents used to represent a file. The list is sorted by
the logical block number (ee_block) so that we can easily find the
proper extent information for any file block.

Without this patch, a 69MB file which had just one extent index pointing
to a block with another 6 extents was read in approximately 3 minutes.
With this patch applied the same file can be read in almost 20 seconds.
