2022-06-28dm: core: Use device_foreach_child where possibleSean Anderson4-15/+14
We have some nice macros for iterating over devices in device.h, but they are not used by the driver core. Convert all the users I could find. Signed-off-by: Sean Anderson <seanga2@gmail.com>
2022-06-28dm: core: Provide fallbacks for ofnode_conf_read_...Sean Anderson1-24/+42
Because fdt_get_config_str et al. were moved/renamed to ofnode_conf_read_str, they now depend on CONFIG_DM as well as CONFIG_OF_CONTROL. Add some fallback implementations, preventing a linker error when CONFIG_SPL_OF_CONTROL and CONFIG_SPL_ENV_IS_IN_MMC are enabled and CONFIG_SPL_DM is disabled.

2022-06-28sandbox: usb: Fix out-of-bounds read when fd=-1Sean Anderson1-1/+4
sandbox_flash_bulk uses priv->read_len to determine if priv->buff contains the response data (such as from SCSI_INQUIRY). However, if priv->fd=-1 in handle_read, then priv->read_len is not set even though we are going to PHASE_DATA. This causes sandbox_flash_bulk to try and read len bytes from priv->buff, which likely goes past the end of the buffer. Fix this by always setting priv->read_len even if we aren't going to read anything.

2022-06-24microblaze: Add support for run time relocationMichal Simek9-4/+216
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 Simek1-0/+166
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.
