Prior to commit 5ba534d247d418 ("arm: Switch 32-bit ARM to using generic global_data setup") we used to have assembly code that configured the malloc_base address.
After this commit we use the board_init_f_mem() function in C to setup malloc_base address.
However the ifdef logic has a problem that prevents malloc_base to be configured in the SPL case.
Would you mind rewording this a bit to avoid confusion? The point here is that a deliberate choice was made to support only early malloc() or full malloc() in SPL, but not both. The point of your change is to allow both to be used, one after the other, in SPL.
This issue has been observed in a Congatec board, where we need to retrieve the manufacturing information from the SPI NOR (the SPI API calls malloc) prior to configuring the DRAM. In this case as malloc_base was not configured we always see malloc to fail.
Adjust the ifdef logic so that malloc_base is always configured when CONFIG_SYS_MALLOC_F is set.
