Platforms wanting to use different TZDRAM_BASE, can add 'TZDRAM_BASE=
<value>
'
to the build command line.
The Tegra platform code expects a pointer to the following platform specific
structure via 'x1' register from the BL2 layer which is used by the
bl31_early_platform_setup() handler to extract the TZDRAM carveout base and
size for loading the Trusted OS and the UART port ID to be used. The Tegra
memory controller driver programs this base/size in order to restrict NS
accesses.
typedef struct plat_params_from_bl2 {
/
* TZ memory size *
/
uint64_t tzdram_size;
/
* TZ memory base *
/
uint64_t tzdram_base;
/
* UART port ID *
/
int uart_id;
} plat_params_from_bl2_t;
