This commit introduces the PDMA (Peripheral DMA) driver for K230 SoC, providing essential DMA capabilities for peripheral data transfers. Key features implemented: 1. PDMA channel request/release management 2. Channel start/stop control 3. Interrupt callback registration 4. Data transfer between device ports and DDR memory The driver includes: - Core driver implementation (drv_pdma.c/h) - Build system support (SConscript) - Basic test cases (test_pdma.c) Tested with: - PDMA channel request/release - DDR to UART TX FIFO transfers - UART RX FIFO to DDR transfers Signed-off-by: eatvector <2302147681@qq.com>
Fixes: 62f3fb4: fix(kernel)/improve(utest):fix the legacy issue related to the length of the object name version #10537 After this patch, if length of object name exceeds (RT_NAME_MAX - 1), RTT will assert and oops when runing, but not in period of building. Though I don't think it's a good solution, but don't want to argue more about this. Old RT_NAME_MAX is 8 for k230, and some object names, such as "hwtimer0", which name length is 8, breaking the new rule. Just update configuration of k230 bsp and increase RT_NAME_MAX from 8 to 16, which should be long enough for k230. Signed-off-by: Chen Wang <unicorn_wang@outlook.com>
