2022-01-05microblaze: branch to base vector address on resetOvidiu Panait1-2/+4
Current code assumes that the vector base address is always at 0x0. However, this value is configurable for MicroBlaze using the CONFIG_XILINX_MICROBLAZE0_VECTOR_BASE_ADDR Kconfig option. Update the reset routines to branch to this location instead.

2022-01-05microblaze: start.S: add support for configurable vector base addressOvidiu Panait1-26/+32
Current code assumes that the vector base address is always at 0x0. However, this value is configurable for MicroBlaze, so update the __setup_exceptions routine to work with any vector base address. The r4 register is reserved for the vector base address inside __setup_exceptions and the function prologe/epilogue are also updated to save and restore r4.

2022-01-05microblaze: drop CONFIG_SYS_RESET_ADDRESS macroOvidiu Panait1-3/+1
Microblaze is one the last two users of the CONFIG_SYS_RESET_ADDRESS macro (the other is arch/powerpc/cpu/mpc8xx/cpu.c, but the macro is not defined anywhere in powerpc code, so it should be removed there too). Replace CONFIG_SYS_RESET_ADDRESS usage in start.S with CONFIG_SYS_TEXT_BASE. If the reset address should really be user-configurable, a new Kconfig option could be added.

Microblaze has three boot modes defined in microblaze/include/asm/spl.h, but only booting from NOR flash is currently useable.

2022-01-05microblaze: u-boot.lds: replace __end symbol with _endOvidiu Panait4-6/+6
board_fdt_blob_setup() uses the _end symbol to find the dtb in the non-spl case. In order to allow microblaze builds to compile successfully with CONFIG_OF_SEPARATE, the _end symbol must be defined.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass3-0/+3
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.
