2013-07-10ARMv7: De-uboot-ify Exynos5250 codeStefan Reinauer
When starting the Exynos5250 port, a lot of unneeded u-boot code was imported. This is an attempt to get rid of a lot of unneeded code before the port is used as a basis for further ARM ports. There is a lot more that can be done, including cleaning up the 5250's Kconfig file.

2013-04-10exynos5: Re-factor I2C codeDavid Hendricks
This re-factors the Exynos5 I2C code to be simpler and use the new API, and updates users accordingly. - i2c_read() and i2c_write() functions updated to take bus number as an argument. - Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and i2c_write(). If a chip needs special handling we should take care of it elsewhere, not in every low-level i2c driver. - All the confusing bus config functions eliminated. No more i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this is handled automatically when the caller does a transaction and specifies the desired bus number. - i2c_probe() eliminated. We're not a command-line utility. - Let the compiler place static variables automatically. We don't need any of this fancy manual data placement. - Remove dead code while we're at it. This stuff was ported early on and much of it was left commented out in case we needed it. Some also includes nested macros which caused gcc to complain. - Clean up #includes (no more common.h, woohoo!), replace debug() with printk().

2013-04-09replace device/i2c.h with simpler versionDavid Hendricks
The existing header was imported along with the Exynos code and left mostly unchanged. This is the first patch in a series intended to replace the imported u-boot I2C API with a much simpler and cleaner interface: - We only need to expose i2c_read() and i2c_write() in our public API. Everything else is board/chip-dependent and should remain hidden away. - i2c_read and i2c_write functions will take bus number as an arg and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to error and end up cluttering the code since the user needs to save the old bus number, set the new one, do the read/write, and restore the old value (3 added steps to do a simple transaction). - Stop setting default values for board-specific things like SPD and RTC bus numbers (as if we always have an SPD or RTC on I2C). - Death to all the trivial inline wrappers. And in case there was any doubt, we really don't care about the MPC8xx. Though if we did then we would not pollute the public API with its idiosyncrasies.

2013-02-07armv7/snow: Remove power_init from bootblock.Hung-Te Lin
The power_init is not required on Exynos 5250 (snow) in bootblock stage. To get a cleaner and faster bootblock, we can remove it. Note, power_init internally calls max77686 and s3c24x0_i2c, so both files are also removed. Verified to boot on armv7/snow.

Remove duplicated / testing code and share more driver for bootblock, romstage and ramstage. The __PRE_RAM__ is now also defined in bootblock build stage, since bootblock is executed before RAM is initialized.
