The short version of the original commit is that some i2c devices cannot
be probed via read as they NAK the first cycle, so try and probe via a
write that we abort before it writes to the device. This however is not
allowed by the TRM for any of these parts. The section on I2C_CON
(table 17-35 I2C_CON for am/dm37x for example) says you must not change
the register while STT has been set. On these parts, the unpredictable
behavior that the chip exhibits is not problematic. On OMAP4 however it
results in the chip being in a bad state:

tegra: seaboard: disable SPI, move environment to eMMC
The SPI hardware on Seaboard is too broken to use; it is muxed with the
console UART and requires evil interactions between the SPI and UART
drivers to work even partially. The current code in U-Boot is not
sufficient to make this work correctly; auto boot is aborted due to
corruption in the UART RX channel interrupting it.
Instead, move the environment to eMMC, at the end of the second boot
sector. This should not conflict with any other eMMC usage, irrespective
of whether the board boots from SPI, NAND, or eMMC: if U-Boot is stored
in eMMC, it will be stored well below this location. The kernel only
uses the general area of the eMMC once booted, not the boot sectors.
Boards that are derivatives of Seaboard don't have the muxing issue,
and should/could have a separate U-Boot configuration file that does
enable SPI if desired.
Alternatively, the environment could be stored in NAND flash, but we
currently have no driver for that controller.

both ext2 and FAT filesystems are supported, the boot script may exist

boot.scr.
When booting over the network, it is assumed that boot.scr.uimg exists
on the TFTP server. There is less flexibility here since those setting
up network booting are expected to need less hand-holding.

video: cfb_console: flush dcache for frame buffer in DRAM
Data cache flushing is required for frame buffer in RAM to fix the
distorted console text output. Currently this text distortion is
observed with cfb on beagleboard and N900 when running with data
cache enabled.
console_back() is called only from video_putc() which already turns
the cursor off at the beginning and turns it on at the end, so there
is no need to change the cursor in console_back().
The AP-SH4A-4A board has SH7734, 64MB DDR2-SDRAM, USB,
Ethernet, and more.
This patch supports the following functions:
- 64MB DDR2-SDRAM
- 16MB NOR Flash memory
- Serial console (SCIF)
- Ethernet (SH-Ether with Gigabit)
- I2C
