sandbox: Add a way to show the sandbox memory-mapping

2024-11-04T03:27:12Z

This is mostly hidden in the background, but it is sometimes useful to look at it. Add a function to allow this. Signed-off-by: Simon Glass

arch: Use CONFIG_XPL_BUILD instead of CONFIG_SPL_BUILD

2024-10-11T17:44:47Z

Use the new symbol to refer to any 'SPL' build, including TPL and VPL Signed-off-by: Simon Glass

sandbox: Implement reference counting for address mapping

2024-09-18T19:01:00Z

An address may be mapped twice and unmapped twice. Delete the mapping only when the last user unmaps it. Fix a missing comment while here. Signed-off-by: Simon Glass

sandbox: Unmap old tags

2024-09-18T19:01:00Z

So far unmapping has not been implemented. This means that if one test maps a pointer to an address with map_sysmem(), then a second test can use that same pointer, by mapping the address back to a pointer with map_to_sysmem(). This is not really desirable, even if it doesn't cause any problems at the moment. Implement unmapping, to clean this up. Signed-off-by: Simon Glass

sandbox: Update cpu to use logging

2024-09-18T19:01:00Z

Use log_debug() instead of including the function name in the string. Add one more debug for PCI. Signed-off-by: Simon Glass

sandbox: fdt: Avoid overwriting an existing fdt

2024-08-09T22:03:19Z

Since the removal of OF_HOSTFILE logic in board_fdt_blob_setup(), the logic for obtaining the DT is handled in the OF_BOARD option. If a devicetree comes from a bloblist it is immediately overwritten by this function. Fix this by skipping the function if a devicetree is already present. This is sort-of a fix for e7fb7896 ("sandbox: Remove OF_HOSTFILE") but it has only come to light since bloblist was added, so I have not added a Fixes tag. Unfortunately it is not possible to report the correct FDT source with the current code. It might be best to use an error-return code for board_fdt_blob_setup() so that an error can be reported if the board does not provide the DT. Signed-off-by: Simon Glass

Merge patch series "Complete decoupling of bootm logic from commands"

2023-12-21T21:10:00Z

Simon Glass says: This series continues refactoring the bootm code to allow it to be used with CONFIG_COMMAND disabled. The OS-handling code is refactored and a new bootm_run() function is created to run through the bootm stages. This completes the work. A booti_go() function is created also, in case it proves useful, but at last for now standard boot does not use this. This is cmdd (part d of CMDLINE refactoring) It depends on dm/bootstda-working which depends on dm/cmdc-working

sandbox: bootm: Enable more bootm OS methods

2023-12-21T21:07:52Z

It is useful for sandbox to build as much code as possible. Enable support for booting various other operating systems. Add the missing cache functions. These operating systems do not actually boot on sandbox, of course. Signed-off-by: Simon Glass

sandbox: Audit config.h and common.h usage

2023-12-21T13:54:37Z

Remove and replace common.h and config.h in sandbox when it's not needed and add some explicit includes where needed. Reviewed-by: Simon Glass Signed-off-by: Tom Rini

sandbox: Add a dummy dcache_status() function

2023-06-21T20:54:25Z

This adds dcache_status() so that code using it can build without error on sandbox. This is required in preparation of adding cache handling into get_ram_size function. Signed-off-by: Emanuele Ghidoli Signed-off-by: Francesco Dolcini Reviewed-by: Simon Glass
