- * Name: nxflat_addrenv_alloc
- *
- * Description:
- * Allocate data memory for the NXFLAT image. If CONFIG_ARCH_ADDRENV=n,

- * then memory will be allocated using up_addrenv_create().
- *
- * Input Parameters:
- * loadinfo - Load state information
- * envsize - The size (in bytes) of the address environment needed for the
- * ELF image.
- *
- * Returned Value:
- * Zero (OK) on success; a negated errno value on failure.
