Add UART asynchronous driver support for Realtek Bee series SoCs, including RTL87x2G, RTL8752H and RTL87X2J. This driver supports: - Asynchronous TX/RX transfers Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>
Convert cached flash addresses to non-cached flash addresses in Realtek Bee DMA driver. Without this conversion, DMA may access an invalid flash mapping and read back 0xdeadbeef. Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>
Enable the UART async API test for Realtek Bee series SoCs. Add configurations for the following boards: - rtl87x2g_evb_a_rtl8762gku - rtl8752h_evb_rtl8752hjl Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>
Add rtl87x2j series in bee dma driver. Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>
Enable the dma loop_transfer test for Realtek Bee series rtl87x2j_evb_rtl8762jth board. Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>

Add SPI driver support for Realtek Bee series SoCs, including RTL87x2G and RTL8752H. This driver supports: - Master and Slave operation modes - Polling, Interrupt, and DMA transfer modes - Transmit (TX) and Receive (RX) functionality Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>
The original test used tx_data (a const char array) directly as the source buffer for SPI transmission. tx_data may be placed in the .rodata section which is not guaranteed to be aligned to the cache line or DMA requirements. This caused DMA transfer failures on platforms with strict alignment constraints. This commit changes the TX buffer from tx_data to buffer_tx. buffer_tx is explicitly declared with __BUF_ALIGN and __NOCACHE attributes, ensuring it satisfies the DMA alignment and cache coherency requirements.

Enable spi_loopback and spi_controller_peripheral tests for Realtek Bee series SoCs. Add configurations for the following boards: - rtl87x2g_evb_a_rtl8762gku - rtl8752h_evb_rtl8752hjl Signed-off-by: Yuzhuo Liu <yuzhuo_liu@realsil.com.cn>
