* xtensa: add support for the xtensa processor architecture [1/2]Chris Zankel2016-08-15-6/+179
| | | | | | | | | | | | | | The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core provided by Cadence. This is the first part of the basic architecture port with changes to common files. The 'arch/xtensa' directory, and boards and additional drivers will be in separate commits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 302c5db ("dm: tpm: Add Driver Model support for tpm_atmel_twi driver") converted the Atmel TWI TPM driver itself to driver model, but kept the legacy-style i2c_write/i2c_read calls. Commit 3e7d940 ("dm: tpm: Every TPM drivers should depends on DM_TPM") then made DM_I2C a dependency of the driver, effectively forcing users to turn on CONFIG_DM_I2C_COMPAT to get it to work. This patch adds the necessary dm_i2c_write/dm_i2c_read calls to make the driver compatible with DM, but also keeps the legacy calls in ifdefs, so that the driver is now compatible with both DM and non-DM setups.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trimslice currently stores its environment at 512KiB into the SPI flash chip. The U-Boot binary has grown such that the size of the boot image (which includes the Tegra BCT, padding, and the U-Boot binary) is slightly larger than 512K now. Consequently, writing the boot image to flash corrupts the saved environment, and equally, writing to or erasing the environment will corrupt the bootloader, which in turn will cause the Tegra boot ROM to enter recovery mode during boot, making it look as if the system is non-operational. Note that tegra-uboot-flasher writes to the environment during the flashing process. Solve this by moving the environment as high as possible in flash. This will allow the U-Boot binary to roughly double in size before this problem is hit again, at which point there's nothing we can do anyway since the binary won't fit into flash. 99% of other Tegra boards store the environment in eMMC and use a negative value for CONFIG_ENV_OFFSET, which already automatically places the environment as near the end of boot flash as possible. The 1 remaining board hard-codes CONFIG_ENV_OFFSET to 2MiB, which allows for plenty more bloat.
