Add CSRNG driver support required by Nord and Shikra platforms.wq Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Disable CSRNG support on Kodiak platforms that do not support the CSRNG hardware. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Disable CSRNG support on Lemans platforms that do not support the CSRNG hardware. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Disable CFG_QCOM_CSRNG by default for Hoya targets. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Enable CSRNG support on Nord platforms. Update the platform configuration to enable the CSRNG driver on Nord. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Enable CSRNG support on Shikra platforms. Update the platform configuration to enable the CSRNG driver on Shikra. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Avoid redefining QCOM_RNG_REG_BASE in Kodiak and Lemans target configuration files. Use the common Hoya definition from arch_config.h and adjust platform-specific offsets to preserve the same effective register addresses. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Read DATA_OUT directly after DATA_AVAIL is asserted. A value of 0x00000000 is a valid random output and should not be filtered out. Waiting for a non-zero value biases the output distribution by excluding a valid result. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Remove the CSRNG initialization log message as it is not required during normal operation. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Force CSRNG enablement on Shikra and define RNG register configuration in the Hoya target-specific configuration files instead of a common architecture configuration. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
Use platform-specific CSRNG base addresses and offsets to avoid redefining common RNG configuration while preserving the effective register addresses. Signed-off-by: mrehman <mrehman@qti.qualcomm.com>
