拉取/合并请求描述:(PR description)
[
为什么提交这份PR (why to submit this PR)
原来的fal对 flash不均匀分布的flash不友好,比如stm32. 明明是一块地址连续的 flash,需要注册出来3个flash设备,fal的分区还不能跨 flash 使用。导致app分区只能放在 128K起始的地址上,造成flash的浪费
你的解决方案是什么 (what is your solution)
为 fal 添加 blocks 机制,支持添加特殊的 block 定义。
使用方式如下,添加了具体的flash的blocks定义,4个16K的blk,1个64K,7个128K。
在什么测试环境下测试通过 (what is the test environment)
在 星火1号上测试通过。
