Every U_BOOT_DRIVER entry must be unique and this driver was re-using the name of the bootcount_spi_flash driver. Change to bootcount_i2c_eeprom. Reviewed-by: Michael Trimarchi <michael@amarulasolutions.com> Signed-off-by: Tom Rini <trini@konsulko.com>
Niko Mauno <niko.mauno@vaisala.com> says: In this series, we first introduce a clean-up where we switch to use predefined bit masks instead of hard-coded values for count and magic halves in the single-word (32-bit) boot count scheme. Then we fix a case of missing boot count value masking in single-word scenario in bootcount.c, which allowed clobbering of the magic half when storing the value. With this change the clobbering preventing behavior becomes consistent with existing single word bootcount storing implementations in bootcount_at91.c and bootcount_davinci.c. Finally, we enable the DM I2C bootcount driver to work also in single word (4 byte) mode, in addition to the pre-existing half-word (2 byte) mode. By default the driver still operates in half word mode as so far, but can now be used alternatively in single word mode by adding 'size = <0x4>;' in the associated device tree node.

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

Add CONFIG_BOOTCOUNT_ALTBOOTCMD so the developer is able to add custom altbootcmd via Kconfig when they enable BOOTCOUNT. With this now in Kconfig, we need to move it from environment files / config.h files and in to the defconfig file. This was done by generating u-boot-initial-env for all platforms before the Kconfig change, to extract altbootcmd values and then again after to compare the result.

Add native support of the bootcount mechanism in the ZynqMP by utilising internal PMU registers. The Persistent Global Storage Registers of the Platform Management Unit can keep their value during reboot cycles unless there is a POR reset, making them appropriate for the bootcount mechanism.
