Detailed Description

JLink-readable snapshot of the most recent RDID probe.

UART on the EK-RA8D2 will not reliably drain ra8_log_* output before demo_panic_halt fires inside lx_nor_flash_format, so the operator cannot see the IS25LX512M JEDEC triplet via the console. Stash the result in a known SRAM word that the developer can read with mem32 <addr> 1 from JLinkExe / Ozone after the panic halt.

Layout (little-endian on Cortex-M85):

magic – k_ra8_xspi_rdid_magic once any probe has run (0 on cold boot before the global has been touched, so the operator can tell stale-RAM values from a real reading).
call_count – number of times internal_bus_init_once has reached the RDID probe step. Bumped before the call so even a hang inside the HAL leaves a visible breadcrumb.
rid_err – ra8_err_t returned by ra8_xspi_flash_read_id (cast to uint32_t). 0 (= k_ra8_ok) means the call returned cleanly.
jedec_id – packed (mfr << 16) | (type << 8) | capacity from the HAL. Expected 0x009D5A1A for the IS25LX512M-JHLE on EK-RA8D2 v1.

Invariant: magic is either 0 (untouched) or k_ra8_xspi_rdid_magic; any other value indicates SRAM corruption / wrong address.
