2022-06-24microblaze: Convert axi timer to DM driverMichal Simek
Move axi timer driver from Microblaze to generic location. Origin implementation was irq based with counting down timer. CONFIG_TIMER drivers are designed differently that timer is free running up timer with automatic reload without any interrupt. Information about clock rates are find out in timer_pre_probe() that's why there is no need to get any additional information from DT in the driver itself (only register offset).

They will be overwritten with data from PVR/dtb if the microblaze UCLASS_CPU driver is enabled. The cpuinfo struct was placed in global_data to allow the microblaze UCLASS_CPU driver to also run before relocation (initialized global data should be read-only before relocation). gd_cpuinfo() helper macro was added to avoid volatile "-Wdiscarded-qualifiers" warnings when using the pointer directly.

2022-06-24microblaze: Add support for run time relocationMichal Simek
Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing issues with function pointer arrays which need to be updated manually after relocation. Building code with -fPIC and linking with -pic will remove this limitation and there is no longer need to run manual update. By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC code will be compiled for full relocation. The patch does couple of things which are connected to each other. - Define STATIC_RELA dependency to call relocate-rela to fill sections. - REMAKE_ELF was already enabled but u-boot file can't be used because sections are empty. relocate-rela will fill them and output file is u-boot.elf which should be used. - Add support for full relocation (u-boot.elf) - Add support for early relocation when u-boot.bin is loaded to different address then CONFIG_SYS_TEXT_BASE - Add rela.dyn and dynsym sections Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original size (550kB to 608kB).

2022-06-24tools: relocate-rela: Add support for 32bit Microblaze relocationMichal Simek
Microblaze is 32bit that's why it is using elf32 format. Relocation code requires to get information about rela and dynsym senctions and also text base which was used for compilation. Code build with -fPIC and linked with -pic generates 4 relocation types. R_MICROBLAZE_NONE is the easiest one which doesn't require any action. R_MICROBLAZE_REL only requires write addend to r_offset address. R_MICROBLAZE_32/R_MICROBLAZE_GLOB_DAT are the most complicated. There is a need to find out symbol value with adding symbol value and write it to address pointed by r_offset. Calculation with addend is also added but only 0 addend values are generated now.

Adding support for new type requires to change code layout that's why move elf64 code to own function for easier maintenance. It also solves the problem with not calling fclose in case of error.

2022-06-24microblaze: Create SYM_ADDR macro to deal with symbolsMichal Simek
Symbol handling depends on compilation flags. Right now manual relocation is used that's why symbols can be referenced just by name and there is no need to find them out.

2022-06-24microblaze: Fix early stack allocationMichal Simek
CONFIG_SYS_INIT_SP_OFFSET macro place stack to TEXT_BASE - SYS_MALLOC_F_LEN but there is no reason to do it now because board_init_f_alloc_reserve() returns exact location where stack should be. That's why stack location is calculated at run time and there is no need to hardcode it via macro. This change will help with placing U-Boot to any address.

2022-06-24microblaze: Fix stack protection behaviorMichal Simek
When U-Boot starts stack protection can be already enabled that's why setup the lowest possible SLR value which is address 0. And the highest possible stack in front of U-Boot. That's why you should never load U-Boot to the beginning of DDR. There must be some space reserved. Code is using this location for early malloc space, early global data and stack.

2022-06-24microblaze: Switch absolute branches to relativeMichal Simek
There is no reason to use absolute branches and use just relative. This change helps with moving binary to different location and start it from there.

2022-06-24tools: relocate-rela: Read rela start/end directly from ELFMichal Simek
There is no need to pass section information via parameters. Let's read text base and rela start/end directly from elf. It will help with reading other information from ELF for others architecture. Input to relocate-rela is u-boot binary and u-boot ELF.

2022-06-24tools: relocate-rela: Use global variablesMichal Simek
Declare rela_start/end and text_base as global variables. It will help with using these variables for ELF decoding. Signed-off-by: Michal Simek <michal.simek@amd.com> Link: https://lore.kernel.org/r/7485b163e92f8f3f754c35f7c88c3314f2212efd.1655299267.git.michal.simek@amd.com

Numbers in comment are shifter which is visible from command which calls them. Also relocate-rela usage is describing them.
